摘要

This paper describes a compact and low cost optically fed antenna for using as a receiver in 5G cellular networks and in distributed antenna systems. It compares the performance of two different topologies of patch antennas tightly integrated with vertical-cavity surface-emitting lasers (VCSELs), without the need for an amplifier stage or matching circuit. Opto-microwave (OM) gain of −21.5 dB at 5...
