Experimental evaluation demonstrates wideband dual-frequency operation in a shared-surface antenna, indicating compact multi-band integration for 5G wireless systems.
A shared-surface dual-band antenna is proposed for 5G operation using characteristic mode analysis (CMA). The surface is the integration of a metasurface at the S-band and a partially reflective surface (PRS) at the Ka-band. The resonant mode of the metasurface is excited by a microstrip-fed slot, and the PRS with a pair of substrateintegrated waveguide (SIW)-fed slots are employed to form a Fabry- Perot resonator antenna (FPRA). Measurements realized on a physical prototype of the antenna show a 10 dB impedance bandwidth of 23.45% and 9.76% and a realized gain that varies from 7.27 to 10.44 dBi and from 11.8 to 14.6 dBi, over the S-band (3.2-4.05 GHz) and the Ka-band (26.8-29.55 GHz), respectively.
