Nikita Gupta1, Niriksha Garg1, Nitin Tayal1, A.S.Gour2, Mukesh Arora2 1Swami Keshvanand Institute of Technology, Management & Gramothan (Student) 2Swami Keshvanand Institute of Technology, Management & Gramothan (Faculty, ECE) Email Id: [email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected] Abstract- In this paper we design a simple microstrip patch antenna having rectangular shape. A good impedance matching condition between the line and patch without any additional matching elements depends heavily on the antenna parameters. The patch is designed to resonate over the frequency 10 GHz. The current and field distributions have been examined. The frequency domain characteristics such as return loss, impedance curve and smith chart have also been analyzed. The results of both the software IE3D and HFSS, have been compared…

My impression of Commercial Radio in Asia

A very significant impression that commercial radio in Asia makes is the strength of commercial radio in the region through the years, especially in comparison with other multi-media platforms. Before the era of the internet, the tri-media through sociological aspects have directly or indirectly created a balance that made the relationship of the three media platforms evenhanded. There are advantages and disadvantages found in print, television as well as in radio, even when there are times that social factors alter the balance temporarily, like the television ad ban and newspaper ad limitations set in Indonesia before which favored commercial radio, income-wise (Anderson, 1984, p. 180). For radio, as well as for the rest of the other forms of media, they…

Power Line Communication

The objective any mining company like TATA STEEL is to reduce the amount of energy used in mining through the increase in employee productivity and safety. Mining operations consist of several tasks. The highest efficiency can only be achieved with full coordination among the persons carrying out these tasks and if the locations of vehicles and people are known by those who coordinate the activities.

Therefore, the establishment of a better communication system for the mine underground is very important and significant to modernize the mine management, increase the labour productivity, and strengthen the security to protect the lives and property of the…

Science Fair Conclusion of How to Make a Crystal Radio

Some of the hypothesis in this experiment supported the results and some of the other hypothesis rejected the results. Some hypothesis which supported the results were that the there would be about one, two, or three channels in the radio, the bobby pin could not replace the germanium diode, and that the crystal radio ware efficient as a normal store bought radio. On experiment two the crystal radio had like 3 stations. The sound was very clear and loud. Also, the bobby pin method did not work. There were lots of hypothesis that did not support the results. Some hypothesis that did not support was that the safety pin could replace the germanium diode. The safety pin wasn’t suitable to…

Microwave Power Transmission

Microwave power transmission (MPT) is one of the applications of microwaves to transmit power from one place to another place without the need for wires. It is the type of the Electromagnetic Radiations, one of the wireless energy transfer methods. Introduction: Firstly, we will talk about the term Microwaves, Microwaves can also be termed as Radio waves having wavelengths ranging from one millimeter to one meter and the frequencies from 300MHz to 300GHz. These are also known as millimeter waves. These waves can also be used for power transmission in such a way, by converting DC power to microwaves and then by using antenna, these are transmitted, and after that rectenna receive those waves and converts them into DC again…

High Frequency Omnidirectional Range

The VHF Omnidirectional Range navigation system, VOR, was probably the most significant aviation invention other than the jet engine. With it, a pilot can simply, accurately, and without ambiguity navigate from Point A to Point B. The widespread introduction of VORs began in the early 1950s and 50 years later it remains the primary navigation system in the overwhelming majority of aircraft. VHF omnidirectional radio range (VOR), is a type of short-range radio navigation system for aircraft, enabling aircraft to determine their position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons with a receiver unit. It uses radio frequencies in the very high frequency (VHF) band from 108 to 117.95 MHz….

Brief History of Radio Broadcasting

According to an online article that was written by Gearbox (2011), the radio has become one of our most simple forms of broadcasting and communication. From helping connect soldiers on the front line of battle to entertaining the commuter on their ride to work, the radio is a part of everyday life. The article gives a brief history of radio broadcasting, in addition to how the low cost and simplicity of technology has become very easy to tune in to your favorite station, even though it was not always that way. The article mentioned that it began in 1887 when a man named Heinrich Hertz discovered radio waves and their ability to transmit code wirelessly. Hertz’s research was followed up…

Problem Definition Report

Since Charles Herrold started broadcasting in California in 1909 and broadcast was carrying audio by the next year, people’s life has been changed by the broadcast (Wiki). After that, a number of radio stations were set up all over the world. From the radio, people could listen to music, listen to the news and they could even go shopping at their home. Additionally, radio station could obtain a respectable income form the advertiser. However, every dog has its day. In 1991, 64% of all commercial radio stations in the USA lost money. In addition, many stations tried playing a blend of current hits and hits from the previous, but the younger listeners did not go for it. The radio stations…

As the technology takes us to another level in the mass media communication, it is important to look back in history and trace the origins of the much advanced world. The current high definition technology being employed in the media industry is a recent phenomenon that was preceded by unrefined technologies of the 20th century. The radio in particular was a major component of the mass media industry and was revered more like the automobile of the 20th century. The radio is regarded as the first ever mass media technological advancement that caught America by storm. The radio turned the Americans to great listeners, entertainers and educators, and joined all the age groups in one common culture. This paper shall…

Lab 6.4: WLAN Placement

Exercise 6.4.1 There are three main types of antennas that can be used for WLAN APs: directional, omnidirectional, and right-angle. Describe each of these antenna types. You can get more powerful antennas that can broadcast longer distances. Why would these antennas be limited in use for standard WLAN placement in a home? An omnidirectional antenna radiates transmissions out and receives transmissions in from all directions, although not equally in all directions. Most of the antennas in this category are thin rods or long flat sticks. Exercise 6.4.2 Using Figure 6-12 as a guide, explain what type of antenna and which channel should be used for each of the APs that are placed. Given the capacity of each AP, is this…

Television and Radio

Isn’t it amazing that people who lived two hundred years ago didn’t have radios or televisions? Today it is difficult to imagine life without these two forms of communication. These technological wonders have many similar characteristics. As you will see, they are also quite different. To start with, both radios and televisions need a source of power in order to run. If you have no electric socket or batteries on hand, you won’t get to watch TV or listen to the radio! Both of these medias make use of airwaves to send their messages, and they offer a range of channels. Concerning appearance, radios and TVs come in all shapes and sizes. There are tiny and big radios and televisions….

Satellite radio: XM versus Sirius

Sirius Satellite Radio Inc (initially called Satellite CD Radio) was one of the two initial players in the satellite radio industry created by two passionate guys David Margolese and Robert Brckman back in 1997 in Canada.
