The most common application of compound reconfiguration is the combination of frequency agility and beam- scanning to provide improved spectral efficiencies.
Frequency reconfiguration is generally achieved by modifying physically or electrically the antenna dimensions using RF- switches.
The antenna which transmits and receives only in the horizontal direction is called as Omni-directional antenna and the antenna which transmits or receives in the particular direction is called as directional antenna.Experimental results, there are some parameters that affect the antenna performance in which two of them have a very noticeable effect in determining the performance of the antenna.SJS Paul College vincere roulette online beat of Engineering and Technology to provide me such a standard educational environment so that I am able to understand the minute concepts in the field of Engineering and Technology.An antenna is generally a transducer which transmits and receives the electromagnetic waves.These antennas are suitable for mobile communications handsets where limited antenna size is a premium.The proposed antenna is simple in structure, and the control circuitry is placed underneath the ground plane.Vishnu vardhana reddy and rahul rana 2009 Copyright 2017 Research and Reviews, All Rights Reserved).Li H, Xiong J, Yu Y, He S (2010) A simple compact reconfigurable slot antenna with a very wide tuning range.
