In this paper, we investigate the feasibility and potential performance of applying an antenna array of directional elements such as horn antennas for mmWave point-to-multipoint communications. We propose a conceptual design of the array, and review options for antenna elements and mechanical steering devices. We then estimate the achievable performance with respect to link data rate and distance,...
A novel reconfigurable partially reflective surface (PRS) antenna is presented in this paper. The beam scanning ability is realized by employing a reconfigurable PRS structure and a phased array as the source. The design achieves a beam switching between −15°, 0°, to 15° with respect to the broadside direction from 5.5 GHz to 5.7 GHz with the realized gains over 12 dBi. Good agreement between the...
This paper illustrates for the first time the ability of leaky-wave antennas (LWAs) in hybrid waveguide printed-circuit technology to provide non-standard simultaneous tapering of the phase and the leakage rate of the constituent leaky mode. This unusual tapering allows synthesis of broadbeam radiation patterns with high rejection out of the prescribed beamwidth , high efficiency focusing near field...
