About This Document

This document-based is on wireless technology which discusses types of antennas such are Omni-directional, Semi-directional and Directional antennas. This document will make you understand by examples of antennas with their strength and weakness. This document also discusses Multiplexing, which is a telecommunication technique that combines multiple signals into one common element that is transferred via a single communication channel.

WIRELESS TECHNOLOGY2Question 1Antennas – devices that are used in wireless communication as propagationcomponents for radio frequency signals. These devices will convert the electricsignals into electromagnetic waves and vice versa which facilitate communicationthrough the radio spectrum where no physical mediums are used. Moreover, antennascan be classified based on their propagation designs which depict certain patterns ashighlighted by their signals lobes [ CITATION NRA10 \l 2057 ].Types of antennas:Omni-directional antennas – these antennas transfer or receive signals in alldirections without any form of restriction. Semi-directional antennas – propagate signals in multiple directions,however, they are limited or restricted in certain directions.Directional antennas – one direction antennas, which means they can onlyferry signals in specific directions [ CITATION Rou17 \l 2057 ].Common examples:Yagi Uda (Yagi) antenna – an example of directional antennas, the Yagi antenna ispopularly used in broadcasting where it acts as a reception tool for television sets. It’saffiliated with long distance application, an attribute caused by its design structure.StrengthsIt has a high sense of directivity which concentrate signals in one direction.High gains due to the attribute above.It’s a simple device made of metallic rods.WeaknessesThe high gain stated above is limited to its size (proportional).Secondly, the gain only reaches 20dB.

WIRELESS TECHNOLOGY3Horn antenna – another directional antenna that is characterised with very highgains. This antenna consists of a pyramid-like structure that flares out toward itsextreme end. This structure increases its signal reception and transmission areaswhich favour its gains. It’s commonly used with ultra-high signals e.g. microwavesignals [ CITATION Rad17 \l 2057 ].StrengthsAs stated above, it exhibits very high gains due to its flare like structure.Secondly, it’s a directional antenna that has high levels of directivity.WeaknessesIt's sometimes complex to implement and install.Similar to other directional antennas, its gains are limited to its size[ CITATIONCar122 \l 2057 ].Cellular antenna – an example of an Omni-directional antenna, this antenna ischaracterised with mobile communication where its size facilitates its integration intosmall devices such as smartphones, tablets and other portable devices. The cellularantenna may transfer signals in all directions, however, its lack of directivity limits itsgains [ CITATION Car122 \l 2057 ].StrengthsIt has an optimal amplifying capability.Secondly, it’s an efficient device that has a convenient structure for mobilecommunication.WeaknessesDirectivity is extremely limited in the device.Secondly, it has limited gains which result in small coverage distance[ CITATION Cis07 \l 2057 ].
