Interference Mitigation Using a Focal Plane Array
We consider the use of spatial filtering algorithms for radio frequency interference (RFI) mitigation in conjunction with a focal plane feed array of electrically small elements. Numerical simulations are used to study the performance of 7 and 19 element hexagonal dipole arrays with a 25 meter reflector at an operating frequency of 1612MHz. Using the maximum-SNR algorithm to generate array weig...
متن کاملNull Steering GPS Array in the Presence of Mutual Coupling
A null steering GPS antenna array is designed in this paper. In the proposed method, the exact full wave antenna radiation properties with the effect of mutual couplings and nearby scatterers are considered to calculate the array steering vector, precisely. Although the proposed method is not constrained by the array geometry and the antenna element specifications, a five patch antenna elements...
متن کاملExperimental Verification of RFI Mitigation with a Focal Plane Array Feed
We demonstrate the use of spatial filtering algorithms for radio frequency interference (RFI) mitigation in conjunction with a focal plane array of electrically small elements. The array consists of a seven-element hexagonal arrangement of thickened dipole antennas with 1600 MHz designed center frequency backed by a circular ground plane at the focal plane of a 3 m parabolic reflector. Rooftop-...
متن کاملPerformance Analysis of Antenna Array Beamformers with Mutual Coupling Effects
Antenna array beamformers suffer from performance deterioration in the presence of mutual coupling (MC) between array sensors. In this paper, we present a theoretical analysis in terms of the output signal-to-interference-plus-noise ratio (SINR) for the performance of antenna array beamformers under MC effects. Based on the model of a distortion matrix to encapsulate the MC effects, a closed-fo...
متن کاملCompact Multiport Array with Reduced Mutual Coupling
A novel design of decoupling network for a compact threeelement array is presented. The proposed decoupling network has simple and compact structure that can be implemented easily with microstrip lines. The conventional microstrip open stubs can be used to match the decoupled ports of the array. The proposed decoupling and matching network is applied to a compact three-monopole array operating ...
