Abstract

The paper proposes a dual-port patch antenna for MIMO applications, optimized using surrogate-based optimization techniques. The antenna uses two resonant modes (TM100 and TM200) to generate two independent radiation patterns. To enhance the bandwidth of TM200 mode, the patch ground plane was realized as a meshed surface. The proposed approach provides 97 MHz of bandwidth, while preserving a low profile of 1.5 mm between the patch and the groundplane (ɛr = 3.5). The numerical optimization involved 12 adjustable geometry parameters.
