Abstract
This paper presents an active photonic antenna concept whereby an interface circuit is introduced in order to integrate the antenna with the photodiode. The operating frequencies ranges are 1.8 to 3.5 GHz which support the GSM 1800, WLAN and WiMAX applications. The simulated and measured results of interface circuit and antenna are presented. Thus, the photonic antenna is developed by integrating photodiode, interface circuit, RF amplifier and printed antenna and fabricated on FR4 board. The experiment was setup and spectrums at desired frequencies were measured. Measurement results show that an active downlink photonic antenna (ADPha) is successfully developed.
