Compact high bandwidth dimension ratio steering-shaped super wideband antenna for future wireless communication applications

摘要

In this article, a compact super wideband (SWB) high bandwidth dimension ratio (BDR) steering-shaped antenna is proposed for future wireless communication applications. The proposed antenna consists of a linearly tapered microstrip-fed circular ring with four elliptical spokes to connect with a central circular disk to form a steering-shaped radiating patch and a rounded cornered notch-loaded rectangular partial ground. The experimental results demonstrate a SWB from 2.3 to 34.8 GHz with a ratio bandwidth (RBW) of 15.13:1 and percentage bandwidth of 175.2% for |S-11| <= -10 dB that are in good agreement with simulation results. The overall size of the proposed antenna is 35 x 35 x 1.6 mm(3)with a BDR of 2403.3. The simulated average peak gain of the antenna is 4.76 dBi. Due to the compact size and good radiation properties over a wide bandwidth, the designed antenna is suitable for civilian and military wireless applications.
