WIDEBAND RADAR CROSS SECTION REDUCTION USING ARTIFICIAL MAGNETIC CONDUCTOR CHECKERBOARD SURFACE

Monopole Antenna Radar Cross Section Reduction with Plasma Helix

In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber without disturbing the antenna performance. The simulations show that radar cross section of simulated antenna is reduced in a wide frequency ...

Waveguide Bandpass Filter Using Artificial Magnetic Conductor

Compact Artificial Magnetic Conductor Designs Using Planar Square Spiral Geometries

Compact spiral artificial magnetic conductors (AMC) have been investigated in this paper. First, single and double spirals are examined to achieve an in-phase reflection at a lower frequency compared to a conventional patch element of the same size. However, these two designs generate a large cross polarization. The cross polarization affects the operating frequency and bandwidth. In order to e...

Design of Compact Artificial Magnetic Conductor Using Planar Square Spiral

When a plane wave illuminates an electromagnetic band-gap (EBG) structure, the reflection phase continuously changes from 180° to -180° as the frequency increases. Especially at a certain frequency where the reflection phase is 0o, the surface shows the same property as a perfect magnetic conductor (PMC). The PMC material does not exist in nature, b u t an artificial magnetic conductor (AMC) ca...

Novel Artificial Magnetic Conductor for 5G Application

A design of novel bendable Artificial Magnetic Conductor (AMC) structures has been presented in this paper in two selected of frequencies at 5G application. These designs started with a square patch shape and continued with the combination of circular and Jerusalem shape which resonate at a frequency of 18 GHz and 28 GHz. Details of the theory and the structures of AMCs are explained. The refle...
