Broadband Circularly Polarized Cross Shaped Slot Antenna with an Improved Feedline

Progress In Electromagnetics Research C, Vol. 74, 141-149, 2017
Abstract
A broadband circularly polarized cross-shaped slot antenna with a parasitic cross-shaped patch and an improved feedline is proposed for wireless applications between 3-6 GHz. In order to achieve a wide axial ratio bandwidth that is totally enclosed within a wide impedance bandwidth, a wide cross slot in the ground plane and an L-shaped strip attached to the lower section of the feedline are employed. This design presents a technique for achieving an axial ratio (AR) bandwidth for a single fed antenna that is wider than most of the single fed slot antennas that currently exist. The proposed antenna with a compact size of 30 mm × 30 mm × 1.6 mm is fabricated and measured. A measured broadside 3 dB axial ratio bandwidth of 68.7% (3.1-6.35 GHz) within a measured impedance bandwidth of 84.1% (2.61-6.4 GHz) for S11 < -10 dB is obtained. A measured peak gain of 3.8 dBi is obtained within the axial ratio bandwidth. The obtained results show that the antenna can be used for wireless devices that operate in the 3.3-3.8 GHz and 5.15-5.35/5.725-5.825 GHz (specified by IEEE 802.11a) bands for wireless standard technologies.
