Polarization in Antenna Polarization is the basic thing used in transmission antennas for the propagation and reception of the signals. As we know that antenna emits electromagnetic waves in the space for the communication purposes. These two types of waves as depicted by the name Electro-Magnetic is a combination of electrical and magnetics fields. These two waves are mutually orthogonal i.e. oriented at an angle of 90o with each other. The general wave form is given as Fig: Electromagnetic…

1.1 Overview: In antenna theory of analysis and design, the most forward looking topic is microstrip patch antenna. Microstrip patch antennas are made to have many different geometrical shapes and dimensions but among all the shapes of microstrip patch, four of them are most common than another that are square, rectangular, dipole and circular. They are employed in wide range of modern applications because of their easiness to design and compatibility with printed-circuit technology. The basic…

supporting explanation with research) Scientific processes that lead to the development of the cell phone are as follows. Observation and measurements: 3 The telephone invented by Alexander Graham Bell in 1876. Hypothesis: Could voice be transmitted via radio waves and be utilized via a mobile device? Experiments: Reginald Fessenden…

During an experiment conducted a 16-channel telemetric electroencephalogram was used to record electroencephalogram (EEG) changes during the exposure of the human skull to electromagnetic frequencies from a cell phone. The area of the ipsilateral eye that was more concentrated on when being exposed to the EMF. In the period of ten to fifteen seconds there wasn’t any change. After twenty to forty seconds a slow wave activity began to show and…

designing a modified network planning for an LTE services using multiple eNodeBs for an indoor premises (shopping complex). We are also going to compare the noise limited and interference limited systems along with its interference synchronization in radio access network. To accomplish these objectives, we are going to perform the following tasks: 1. To expand the indoor design of LTE service for the shopping complex, we are going to use seven femtocell and will perform the SINR…

2 OFDM SYSTEM:- OFDM system is divided into three parts 1. multi carrier modulation 2. frequency division multiplexing 3. Orthogonal frequency division multiplexing. 1.Frequency division multiplexing:- Frequency Division Multiplexing is a form of signal multiplexing which involves assigning non – overlapping frequency ranges or channels to different signals or to each user of a medium. A gap is left between each of these channels to ensure that the signal of one channel does not overlap with…

I am a sports analyst for a radio station in Ghana called Gaskiya Fm transmitting on the frequency 105.5 mhz and on tunein as Gaskiya Fm. Recently, there was a conflict encountered at Gaskiya Fm and I will like to share it and analyse it with the critical thinking tools studied at UoPeople. A standard radio sports show in Ghana should last for a duration of two hours. 30 minutes dedicated to foreign news, 30 minutes for local news, 40 minutes for analysis of the news and 20 minutes for…

Armstrong, a brilliant innovator of radio technology, spent more than twenty years fighting the legal battle between himself and de Forest as to who was the rightful patent-holder of the Audion circuit system that Armstrong had created using de Forest’s Audion. As Armstrong began to move on and discovered FM radio, Sarnoff did everything and anything in his power to prevent Armstrong’s FM frequency radio from being mass-produced. He didn’t do this in the name of radio technology, but because it…

2G RADIO CHANNEL:  INTRODUCTION: Telecom is currently time to tackle a basic part in the arrival of information beginning with one point then on the following point.it be in a sort of verbal structure, in a kind of text, yet now there is a package of new improvements present in telecom with the guide of? i video calling too possible. New organizations and progressions learn through transparent the front line exertion and client longing to increment and contention in the middle of manager and…

that was used frequently was radio propaganda. Both the United States and the Soviet Union depended on Radio Propaganda to convey certain ideals to many individuals. Radio propaganda was used frequently during the early stages of the Cold War since many people owned radios. The United States…
