Horn Antennas With Integrated Notch Filters
IEEE Transactions on Antennas and Propagation, 2015In this communication, we present the design of filtering horn antennas with band-stop characteristics obtained through the use of electrically small magnetic resonators. In particular, a split-ring resonator (SRR) etched on a Rogers Duroid RT5870 dielectric substrate is inserted within the metallic flare of the horn at a proper distance from the ...

Kalman filter for adaptive antennas
Wuhan University Journal of Natural Sciences, 1998Adaptive control algorithm is a key technique for an adaptive array. It is necessary to find a fast and efficient algorithm for gaining rapid interference suppression. Convergence speed of conventional gradient-based algorithms is extremely slow and very sensitive to eigenvalue spread of autocorrelation matrix.

Integration of filters and microstrip antennas
IEEE Antennas and Propagation Society International Symposium (IEEE Cat. No.02CH37313), 2003A new implementation of the integrated antenna-filter module has been proposed that is based on the single material technology and uses the same substrate for both the antenna and filter layers. An X band device has been designed on the low permittivity substrate and examined for X band operation. This example proves the feasibility of achieving a well-

A self-oscillating active filtering antenna
2014 International Symposium on Antennas and Propagation Conference Proceedings, 2014A self-oscillating active filtering antenna is presented in this work. In the positive feedback path of an oscillator, a two-way filtering power divider is incorporated. One of the output port of the power divider is electromagnetically coupled to an antenna, and the other output port is used for feedback.
