ABSTRACT The advancement of wireless communication is markedly accountable from the past two decades, In the past, various sustaining designs of reconfigurable multiband antennas for different wireless services have come into existence. The smart and adaptive frameworks is required reconfigurable antennas for the great utility. Now a days, a high quality of communication with reduced size is required for new generation wireless system. The re-configurability offers plethora of advantages in wireless networks such as 4G & 5G networks. A reconfigurable antenna should have sufficient number of active elements, which helps to achieve the reconfiguration in antenna characteristics. The characteristics of antenna can be manipulated and revamped by changing the current flow in the radiating element of antenna with the help of active elements/switches such as; MEMS switch, varactor diode and p-i-n diodes. These high-quality active elements are responsible to increase the biasing complexity as well as cost of the networks. A reconfigurable system along with minimal interference level over the fixed or non-reconfigurable transceivers has been discussed in detail. Therefore, this work attempts to present a review of reconfigurable antennas for state of the art wireless techniques mainly focus from 2005 to 2018. |
