Abstract

A 'Chakra-shaped' structure antenna with multiple slots are used to resonant the higher oscillation in the broadband range., and partial (PGP) ground plane is also used for better resonance at lower frequencies. The designed antenna exhibits low return loss from 3.5 to 10 GHz. The antenna was constructed with an FR4 substrate., and a 50Ω A-type connector feeds it. The optimum dimensions of the 'Chakra-shaped' antenna are 11 *14*1.5 cubic millimeters. The relative bandwidth of the designed antenna is 96%. The designed structure also receives a stable radiation pattern. 'Chakra-shaped' structure has a high gain of up to 2.1 dB and antenna efficiency up to 77.9%. The proposed structure is compact., lightweight., and easy to fabricate. The structure is compatible with use in broadband which includes satellite mobile communication (4/6 and 7/9 GHz)., defense communication from 8-10 GHz (partial X-band)., WiMAX-5.5 GHz., and WLAN-5.2/5.8GHz applications.
