Abstract
In this article, we present a novel UWB reconfigurable notch band antenna based on liquid metal switching capability. The band rejection reconfiguration is achieved by switching the two pentagonal shaped stubs with the circular patch. The mechanism of switching is based on controlling the liquid metal in microfluidic channels by applying voltage on circular patch and pentagonal shaped stub. The proposed antenna has a simple configuration and compact size of 27 × 30 mm2 that covers UWB (3.1-10.8 GHz) and also generates the band rejection in WiMAX (3.5 GHz) and WiFi (5.2 GHz) by changing state of the switches that is suitable for cognitive radio system.
