    This study presents a novel two-array MTS-gridded MIMO antenna with dual circular polarization (CP) bidirectional capabilities for full-duplex communications. The proposed antenna consists of two mirrored clusters, each comprising a single-element antenna formed by a 3 × 4 MTS-gridded element array, a circular patch, and a ground plane. The antenna demonstrates a wide measured return loss bandwidth (RLBW) of 56.46% (5 - 8.67 GHz), axial ratio bandwidth (ARBW) of 18.15% (6.26 - 7.44 GHz), and strong isolation below -22 dB. Peak gains of 6.5 dBic and 6.55 dBic were observed at 6.6 GHz and 6.54 GHz for Ports 1 and 2, respectively. Furthermore, the low envelope correlation coefficient (< 0.005) and high diversity gain (> 9.985 dB) validate its effectiveness for multi-port applications. The bidirectional radiation pattern and dual circular polarization support simultaneous transmission and reception, making the design well-suited for full-duplex MIMO operation.

    This paper presents a compact ultrawideband circularly polarized Archimedean spiral antenna integrating a cavity-backed structure with a circular EBG reflector. The hybrid design enhances gain, suppresses backward radiation, and improves directivity, particularly below 3.0 GHz. The antenna covers 1.5-9.0 GHz with |S11| ≤ -10 dB and axial ratio ≤ 3 dB. Simulations show peak gain over 11.96 dBic at 6.5 GHz and a front-to-back ratio improvement due to the cavity. The proposed structure is well-suited for GPS, Wi-Fi, and IoT applications.

    This paper presents the design and optimization of a circularly polarized UHF RFID reader antenna. The initial radiator dimensions were set at 130 mm × 130 mm, and the feed position was fine-tuned, with simulations identifying x, y = 24.5, 24.5 mm as the optimal location for impedance matching. Further optimization focused on reducing the ground plane size, with a 170 mm × 170 mm ground plane providing the optimal balance, ensuring an axial ratio below 3 dB and stable |S| (dB) response across the 920-925 MHz frequency band. The final design demonstrated an improved radiation pattern and sufficient gain, making it an effective solution for UHF RFID reader applications.
