In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the antenna surface and produce reversible modifications of its properties.

What are pattern reconfigurable antennas?

Pattern reconfigurable antenna for wireless applications using parasitic ring. ... The antenna features a rectangular patch which is inset fed by a microstrip transmission line and enclosed in a ring. A partial ground plane and three pin-diodes are used to achieve the reconfigurability performance.

What is reconfigurable microstrip antenna?

Reconfigurability is achieved by inserting PIN diode switches in DMS(defected microstrip structure) `T' slot filter. The proposed antenna is capable of switching between a wide operating band of 3.0 GHz - 10 GHz and six different narrow band operating from 5 GHz to 10 GHz.
