Part A
Types of Antenna
There are numerous 8sorts of antenna developed in a communication system, for
example, yagi-uda, horn, and cellular antenna.
Yagi-Uda Antenna
Yagi-Uda radio wire is otherwise called a yagi-uda RF reception apparatus and it is
kind of receiving wire which is utilized where the large scope of improvement and
directivity are required. There are many authors researched in this antenna and they
estimated that this type of antenna cannot be used for long-distance communication. There
are main three parts of this, for example, reflector, driven and director. All these three
elements are placed on certain distance and reflector is used to receive reflected radio
frequency waves.
Strength
 Large flexibility
 Simple process
 Large gain
 High-frequency response
Weakness
 Low bandwidth
 Increased noise and other distortion losses
 This antenna depends on the weather situation (Han, & Liao, 2014).
