A Review: Techniques and Methodologies Adopted for Reconfigurable Antennas

The integration of multiple radios into a single platform to maximize connectivity is a useful requirement in advancement of wireless communication. The parameters of the antenna are modified so that the antenna becomes suitable for any environment then it is called reconfigurable antenna. It is based on modification of frequency of antenna, wavelength etc. The technologies and methodologies such as RF switches, MEMS, PIN diode, varactors and Methodologies like total Morphing Geometry, Matching Morphing Geometry and smart Geometry Configuration.
