摘要：
The design of a hexadecagon circular patch (HDCP) antenna for dual-band operation is presented in this paper. The proposed antenna operates at two resonating frequencies 13.67 GHz, 15.28 GHz with return loss of −42.18 dB, −38.39 dB, and gain 8.01 dBi, 6.01 dBi, respectively. Impedance bandwidths of 854 MHz (13.179–14.033 GHz) and 1140 MHz (14.584–15.724 GHz) are observed for the dual bands, respectively. To produce circular polarization, the HDCP antenna is incorporated with ring and square slots on the radiating patch. The defected ground structure (DGS) is considered for enhancement of gain. Axial ratio of the proposed antenna is less than 3 dB, and VSWR ≤ 2 for dual bands. The measured and simulated (HFSS, CST) results of the HDCP antenna are in agreement. The HDCP antenna can work at Ku band for satellite communications. © 2018, Electromagnetics Academy. All Rights reserved.
