WIRELESS NETWORKING AND COMMUNICATION1Question 1Defining different kinds of antenna:1. Horn Antennas: A microwave horn or horn antenna is that kind of antenna whichis consist of flaring metal waveguide shaped like a horn for the radio waves to be directed ina beam. These antennas are used at microwave frequency and UHF which are more than300MHz (Esquius-Moroteet al., 2013). There are several types of horn antennas and itscatagories the corrugated horn antenna, conical horn and pyramid antennas. The transitionbetween free space and wave guides are affected on the enabling of this antenna.Following are the strength and weakness of the Horn antennas:StrengthWeaknessGood impedance matchFlare angled and length of the flare must notbe very smallSmall minor lobes are formedDecides the directivityGreater directivityDesigning of the flare angleNarrow beam widthAvoids the standing waves2. Helical Antennas: Helical antenna consists of wire that can conduct in the form ofa helix. Helical antennas are mostly grounded over a plane ground. Thus, feed line getsconnected between the ground and the bottom of the helix. The frequency by which thehelical antenna operates is from 30MHz to 3GHz (Ju& Zhang, 2014). Following are the strength and weakness of the Helical antenna:StrengthWeaknessWider bandwidthEfficiency decreases with the number ofturns

WIRELESS NETWORKING AND COMMUNICATION2Provide polarized waves circularlyThe antenna size is large so it requires morespaceHave simple designAlso can be used at HF and VHF bandsHighest directivity3. Yagi Antennas: Yagi antennas are also known as the Yagi-Uda antenna, which is has beenconstructed in such a way that is simple but also has higher gain that is greater than 10dB(Esquius-Moroteet al., 2013). This antenna can be operated in HF to UHF bands that are from3MHz to 3GHz, therefore has smaller bandwidth. Basically used in the roof tops. Following are the strength and weakness of the Yagi antenna:StrengthWeaknessHigh directives is achievedProne to noiseHigh gain is achievedExperiences degradation of the electricalcharacteristicsLess amount of power is neededFrequency range and bandwidth is limitedEasy of handling and maintenance Prone to atmospheric effectsBroader coverage of frequency4. Cellular Antenna: Cellular antennas are also called the cell antennas. These are basicallyused to make conjunction with the help of several power boosters like inline amplifier andsome of them are directly connected with the cell phone adapter cables (Honget al., 2014). Following are the strength and weakness of the Cellular antenna:StrengthWeaknessWireless serviceEffects the environment Can be used remotelyData and signals might get lost some times
