A new optical technique for feeding microwave microstrip antennas

摘要

In the literature, several techniques have been presented for feeding microstrip antennas with RF-modulated lightwave signals via optical fiber. This paper describes a new technique, the novelty of which is that it uses integrated optical waveguides as the main feed network of the electrooptic antennas. We use the basic spectral domain method to analyze the antennas and we compute the overlap fields integral to point out lightwave and microwave electrooptic interaction.
