This paper presents a novel multiport antenna tailored for 5G millimeter-wave (mm-Wave) applications. The proposed design features orthogonally arranged radiating elements to ensure compactness with an overall footprint of just 20 × 26 mm2. A key innovation is the integration of a frequency selective surface (FSS) layer placed above the antenna system to enhance gain and isolation without increasing complexity. This FSS enhances gain by 1.5 dB across the band, achieving a peak gain of 7.5 dBi at 41 GHz. The antenna operates across the entire Ka-band (22–46 GHz), delivering efficiency exceeding 80% and maintaining isolation above 20 dB. Key multiport antenna performance parameters including diversity gain (DG = 10) and envelope correlation coefficient (ECC <0.005) align with performance benchmarks, and experimental measurements validate simulation results. The unique combination of orthogonal element placement and FSS enhancement positions this antenna as a robust solution for next-generation 5G applications.

Abstract
This paper presents a novel multiport antenna tailored for 5G millimeter-wave (mm-Wave) applications. The proposed design features orthogonally arranged radiating elements to ensure compactness with an overall footprint of just 20 × 26 mm2. A key innovation is the integration of a frequency selective surface (FSS) layer placed above the antenna system to enhance gain and isolation without increasing complexity. This FSS enhances gain by 1.5 dB across the band, achieving a peak gain of 7.5 dBi at 41 GHz. The antenna operates across the entire Ka-band (22–46 GHz), delivering efficiency exceeding 80% and maintaining isolation above 20 dB. Key multiport antenna performance parameters including diversity gain (DG = 10) and envelope correlation coefficient (ECC <0.005) align with performance benchmarks, and experimental measurements validate simulation results. The unique combination of orthogonal element placement and FSS enhancement positions this antenna as a robust solution for next-generation 5G applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
