Abstract-In the military applications, electro-optics and electromagnetics features of the cloths made of special textile structures and certain fibers play an important role in producing textile characterized with high ability of camouflage. This means not allowing enemy to precisely determine the moving and mute targets using available radar or any other electro-optics sensors. The aim of this paper is to determine the effect of the composite fabrics structure parameters on the fabrication of a resistive sheet used in many radar applications. The objective sheet can be used as a lossy sheet in absorbing mechanism. The radar absorbing mechanism has been studied with emphasis on the single layer structure mechanism with a resistive sheet. Fabric structure of the resistive sheet was accurately chosen and coated with lossy material. For coating, several formulas of fabrics using carbon black were tested to determine the best chemical treatment in accordance with their functional performance. Lab measurements have been done to get optimum formulas and optimum fabrics structures for high radar absorption performance.

“…The former can reduce RCS all the time, no matter whether an antenna works or not. Examples of these techniques are lumped loading technique [1,2], covering lossy substrates technique [3] and adding slot and shorting post technique [4,5]. This kind of techniques affects the antennas' structure or radiation more or less.…”

Abstract-In this paper, a new Yagi-Uda substrate is proposed to obtain radar cross section (RCS) reduction. The Yagi-Uda substrate on which three kinds of metal microstrip lines are etched is put directly on the top of a patch antenna and can reduce RCS sharply by steering the direction of reflecting wave at resonant frequencies. Using a reconfiguration technique, the antenna can radiate without the substrate's effects. When the antenna does not need to work, the Yagi-Uda substrate works to reduce the RCS of the antenna. Besides, the resonant frequencies can be shifted by reconfiguring the Yagi-Uda substrate, so the RCS can be reduced in a broad frequency band.

“…With this technique, RCS can be reduced by changing the structures of the original antennas [1,2]. Radome technology [3,4] is used to protect the antenna and reduce the out-of-band RCS of the antenna.…”

Abstract-Two different kinds of artificial magnetic conductors (AMCs) are used to reduce the out-ofband radar cross section (RCS) of microstrip patch antenna. The principle of this method is based on the high impedance characteristic of the AMC structures. The simulated results show that out-of-band RCS of the proposed patch antenna is much lower than that of the reference antenna over the frequency range of 5-12 GHz. The in-band scattering characteristic of the microstrip patch antenna is analyzed, and two slots are cut on the patch antenna to reduce in-band RCS. Prototypes of the reference and designed antennas are manufactured and tested, and the measured and simulated results of the two antennas are in good agreement.
