Design Investigation of a Novel Dual-Band Circularly-Polarized Microstrip Antenna for 2.4 GHz and 5.7 GHz

Abstract—In this paper, a single-fed multiple slotted square patch antenna is proposed to obtain dual-band Circular Polarization (CP) radiation patterns. Inserting four T-shaped slits at the patch edges of a square microstrip antenna, the proposed antenna is designed and fabricated. The simulation and measurement results including return loss, radiation patterns and Axial Ratio (AR) are presented. Compared to the reported designs in literature, a patch size reduction as large as 32% is obtained. Measured results show that -10 dB bandwidths of return loss for lower-band and higher-band are 71 MHz and 299 MHz respectively. Also, the minimum return losses are -49 dB at 2.497 GHz and -22 dB at 5.887 GHz. Measured results show that AR bandwidths are 13 MHz for lower and 15 MHz for higher band. The introduced antenna is successfully designed and fabricated and the measured results are in a very good agreement with those obtained by numerical investigation.

Index Terms—Dual-band, circular polarization (CP), microstrip antennas, square patch.
