Polarization in Antennas and Radar 来自 ResearchGate 喜欢 0 阅读量: 99 作者: H Nott 摘要: Methods of treating polarization problems in antennas and radar are surveyed. An introduction to antennas is first given, followed by a discussion of wave polarization representation. Polarization matching for...
Today's world of wireless communication revolves around the way of transmitting the signal in the desired direction. Varied gain, varied phase, varied polarization and varied angle microstrip antennas are attractive for mobile communications, radar, electronic detection and covert applicati...
- 《IEEE Transactions on Antennas & Propagation》 被引量: 25发表: 2015年 Ultra-wideband RCS reduction using novel configured chessboard metasurface A novel artificial magnetic conductor (AMC) metasurface is proposed with ultra-wideband 180° phase difference for radar cross section (RCS) reduction. ...
Still, there are some pretty fancy parts here, with a Zynq 7020 FPGA and a boatload of memory on the digital side of the custom PCB, and a host of specialized parts on the RF side. The antennas are pretty cool, too; they’re stacked patch antennas made from standard FR4 PCBs, with...
Adaptive suppression of skywave interference in HF surface wave radar using auxiliary horizontal dipole antennas This report presents the results of a study to evaluate the effectiveness of an adaptive technique using horizontal dipoles to suppress the skywave interfe...

The antenna array may include dipole antennas incorporated within the circuit board and positioned within a close proximity to the ground layer. One or more stubs may be implemented on the circuit board near the dipole antenna array. Each antenna stub may create an impedance in the dipole ...
In cases where the orientation of the radiated electric field is readily determined, such as a dipole, no ambiguity is created. With more complex antenna structures it can be harder to see where the E-plane ought to be, and circularly-polarized antennas don’t have a unique electric field ...

A novel, polarization insensitive, wide-angle and broadband electromagnetic metamaterial absorber, which can cover either a flat or a bent geometry, is presented in this work. The periodic geometry has a unit-cell, which consists of four split ring reson
