Abstract

This paper presents the integration slots and Complementary Split Ring Resonators (CSRRs) in the development of miniaturized, high-gain, dual-band Microstrip Rectangular Patch Antennas (MRPAs) for 5G mobile communication applications. The antennas were designed on a Rogers RT5880 substrate with a thickness of 0.508 mⅿ. Slots and ⅭSRR metamaterial unit cells were integrated into the patch and ground planes, respectively, to achieve size reduction, high gain, and bandwidth enhancement. The design and simulation processes were conducted using ⅭЅΤ Studio Suite 2018. Simulated results of the best-performing antenna showed that integrating CSRRs reduces the MRPA size by approximately 25%, from 330 mm² (16.5 × 20.0 mm²) to 248 mm² (15.5 × 16.0 mm²). The conventional MRPA antenna without slots and CSRRs resonated at 26.59 GHz and 28.0 GHz, offering bandwidths of 0.50 GHz and 0.81 GHz, with corresponding gains of 5.81 dΒ and 9.44 dΒ, respectively. After integrating the slots and CSRRs, the MRPA antenna resonated at 26.75 GHz and 28.0 GHz, with bandwidths increased to 0.52 GHz and 1.10 GHz (enhancements of 4% and 36%), and gains improved to 9.20 dΒ and 11.39 dΒ (enhancements of 58% and 21%), respectively. These enhancements and size reduction make the proposed slotted and CSRR-loaded MRPA antennas suitable for millimeter-wave 5G wireless portable devices.
