Abstract

This paper presents the design, simulation and performance enhancement of a circular microstrip patch antenna working in the Ku band. The three antenna configurations considered were a conventional single circular patch antenna, a stacked circular patch antenna with partial ground and a slotted stacked circular patch antenna. The antennas were designed on a Rogers RO4003C substrate (εᵣ = 3.55, h = 1.6 mm) and analysed using CST Microwave Studio. A conventional antenna has achieved a fractional bandwidth of 6.45% and a gain of 6.73 dBi. Using the stacking technique, the bandwidth was enhanced to 35.3% over the frequency range of 11.667–16.667 GHz, while the gain was reduced to 3.27 dBi. To improve the radiation performance, slot etching was introduced into the stacked antenna, and dual-band operation is achieved with bandwidths of 20.95% (12.6–15.6 GHz) and 5.5% (16.9–17.8 GHz) with increased gain to 6.67 dBi. The proposed slotted stacked antenna achieved a better trade-off between bandwidth and gain even though the bandwidth was reduced compared with the stacked configuration. The results presented in this paper suggest that the proposed antenna is a promising candidate for communication applications in Ku-band
