Abstract
- ABSTRACT A broadband circularly polarized patch antenna with suspended structure is proposed. The suspended patch has a bow-tie structure and a gap-coupled feed. By connecting a resistor load to another gap-coupled feed port at the opposite position, a wide impedance and axial ratio (AR) bandwidths are obtained. The proposed design has a very simple antenna structure with an impedance bandwidth of 44.5% and a 3-dB AR bandwidth of 33.8%, respectively. The results show that the bandwidth of the patch antenna is successfully broadened using the suspended configuration, gap-coupled feed, and resistor loading. © 2014 Wiley Periodicals, Inc.
