Active photonic antenna for wireless communications at 2.4 GHz

Abstract

Active photonic antenna (APhA) designed for 2.4 GHz communication in downlink side is proposed. The APhA consists of photodiode, RF amplifier and band pass filter (BPF) in small package, integrated with RF antenna. The APhA design is simulated using optical communication simulation software at varied fiber length and free space loss (FSL). Performance improvement over passive photonic antenna (PPhA) in term of signal power, SNR, constellation diagram, and BER is achieved, especially at PPhA service boundary.
