3WIRELESS NETWORKING CONCEPT1. IntroductionThe antenna is mainly a device which can be used to convert required signal informationinto an electromagnetic wave. The use of an antenna can be either transmitting or receiving. Atransmitting antenna is a one which converts an electrical signal into electromagnetic wave andradiates them and on the other hand a receiving antenna is a one which converts electromagneticwave from the receiver beam and converts it into electrical signal (John el al., 2016) Antenna canbe also being termed as aerial. Now day’s antennas have undergone many changes with regardsto their shape, size and with its functionality. They can be selected according to the requirementof the user and the according to the role they want the antenna to perform.The report mainly focuses on the overall concept of the antenna technology bringing intoaccount few different antennas with its main strengths and weaknesses. After covering theoverall concept a particular antenna is chosen which would be estimated to play a vital role in thenear future with its implementation and the concepts involved in the process.2. Horn antennaA horn antenna is a category of antenna which can be mainly be considered as a flaredout wave guide which can be implemented in order to improve the directivity and the reductionof the diffraction. In order to improve the directive and the efficiency of the beam, with regardsto the wave guide it should be provided with an aperture extension in which the abruptdiscontinuity which regards to the wave would become gradual transformation. As a result ofwhich the energy would be directed in the forward direction. This concept can be termed asFlaring and this can be implemented with horn antenna (Hua et al., 2016)
4WIRELESS NETWORKING CONCEPTApplication of horn antennaThe antenna is used in astronomical studiesThe antenna is used in microwave applicationsFrequency RangeThe frequency range of operation of the helical antenna is around 30 MHz to 3GHzStrengthThe following are the major strengths of the horn antenna.Greater directivityStanding waves are avoidedSmall minor lobes would be formedMatching with the impedance is goodBand width is narrowWeaknessThe following are the main weakness of the horn antennaThe decision of the directivity is involved in the designing of flare angleWith emphasis on the length of the flare and flare angle it should not be very small.3. Yagi – Uda AntennaThis type of antenna is mainly used the reception of television which is in active rolesince few decades and also playing a predominant role in recent time. The Yagi – Uda antenna is
