Optical beam forming for phased-array antennas

communications spectrum from copper cables, optical fibres, microwaves, radio and electromagnetic compatibility. Our research concentrates on optical signal processing and networks, mobile communications, microwave techniques and radiation from ICs and PCBs [1]. A considerable (and particularly interesting) part of it is related to optical beam forming for phased array antennas, using optical r...

Design and Fabrication of Plasma Array Antenna with Beam Forming

In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes a beam forming smart antenna. An experimental model in UHF...

Reconfigurable Digital multiple beam forming with planar phased array RADAR on FPGA

Beam forming is a signal processing technique used in antenna arrays for directional signal transmission or reception. Phased array radar is very important in modern radar development, and multiple digital beams forming technology is the most significant technology in phased array radar. Digital multiple beam forming on each antenna element about large phased array radar is impossible in proces...

Design of a Ring Resonator-based Optical Beam Forming Network for Phased Array Receive Antennas

A novel squint-free ring resonator-based optical beam forming network (OBFN) for phased array antennas (PAA) is proposed. It is intended to provide broadband connectivity to airborne platforms via geostationary satellites. In this paper, we present the design of the OBFN and its control system. Our goal is to deliver large bandwidth Ku-band connectivity between antennas, mount conformal to the ...
