Abstract

A simple and compact cross-slot wide-band patch antenna for circular polarization with a novel technique for enhancement of bandwidth and
axial ratio is presented. By embedding three proper cross slots in radiating patch of the antenna, both impedance matching, and a good and desired
axial ratio is achieved. Due to low thickness of the proposed antenna about (0.05λ0), the probe inductance is reduced and its effect on the impedance
matching of the antenna can be ignored. Experimental results show that the designed antenna, with a compact size of 30×30×2 mm3, has a suitable
impedance bandwidth of 5.4 to 6.5 GHz for voltage standing wave ratio (VSWR≤2), and the axial ratio less than 3 dB from 5.69 to 5.83GHz, which
is suitable for WLAN (5.725-5.825 GHz) applications
