Abstract

The circular phased antenna array is a common way to generate waves bearing Orbital Angular Momentum (OAM) in the radio frequency band, but the directivity of this antenna is relatively low. To overcome this drawback, in this paper, we use a Fabry-Perot cavity to enhance the directivity of an OAM antenna based on a circular phased array of patch antennas. The Fabry-Perot cavity consists of a ground plane, an air cavity and a partially reflecting surface (PRS) made of metallic strips. Simulation results show that the OAM antenna achieves a directivity of 16.2 dB with an enhancement of 9.2 dB in E and H planes.
