WIRELESS COMMUNICATION2Question 1: DifferencesYagi, horn, cellular antennaYagi antenna is also known as the Yagi-Uda array is the directional antenna which is often used for the communication whenever the frequency is above 10 MHz. This kind of antenna continuesto be popular among the Amateur radio and the Citizen Band radio providers (Ammann & John, 2005). It will be utilized at a number of the surface in the installation of the satellite communications techniques (Ammann & John, 2005). The antenna offers unidirectional radiation in addition to the response pattern, however it concentrates the radiations and the response.StrengthsIt has a gain which allow a lower strength of the signal to be received.It has a directivity which enables the interference levels to be minimized.It design of the antenna is able to filter on the signal noise which is coming from the opposite direction (Chieh, Dick, Loui & Rockway, 2014). This consequently tends to make Yagi’s the right choice when you have a high demand application for example the telecommunications. • It is significantly simpler to aim the Yagi antenna than a few of the other arrays. There construction causes them to be much simpler to mount on the vertical towers.WeaknessesThere is limitation of the bandwidth or the frequency.In case an individual’s wants to have a high gain level, the antenna need to be very long. This kind of antenna experiences a degradation for the electrical characteristics as one moves away from the frequency range (Chieh, Dick, Loui & Rockway, 2014).

WIRELESS COMMUNICATION3Horn antennaThis really is an antenna which consist of the flaring metal waveguide which is shaped similar to the horn to direct the radio waves in the beam (Pelletier, Olvera-Hernandez, Watfa & Ahmad, 2017). The horn has been utilized extensively especially to the UHF and the microwave frequencies, which is above the 300 MHz. StrengthsImpedance matching is very goodIt has a greater directivityThere is narrower beam widthThere is standing waves which are avoided.Weaknesses The designing of the flare perspective determines on the directivity The flare angle in addition to the length of the flare really should not be very small.Cellular antennaThis antenna is utilized in the alignment with the powered signal booster for example the inline amplifier, repeater or even the connected directly to cell phone or maybe other devices which arewith the cell adapter cable or even the coax adapter (Chieh, Dick, Loui & Rockway, 2014).StrengthsThere is increased number of the users, due to the targeted nature of the frequencies of the antenna could be reused allowing on the increased on the user number.
