“…Lumped loading technique has been used to control the RCS of the patch, but the gain of the antenna is often descended. To achieve broadband RCS reduction, a narrow resistive ribbon around the periphery of the patch has been used [1,2]. By using lossy substrates and shorting post, RCS reduction can be realized [3,4].…”

Abstract-A rectangular patch antenna with two circular apertures, a defected ground structure (DGS), and a shorting post is proposed in this paper. The novel structure can reduce the radar cross section (RCS) of the antenna at its operating frequency. At the same time, the return loss of the proposed antenna is maintained, and the RCSs of the patch antenna at the frequencies outside the operating band are also reduced. The proposed antenna is simulated by using high frequency electromagnetic simulation software. The peak of RCSs is reduced about 7 dB and the broadband RCSs are below −30 dB from 2 to 8 GHz. This result is useful for low-RCS antenna application.

“…Although this design can reduce the metal plate RCS over a broad frequency range, it is not suitable for antenna's RCSR. Other techniques, such as loading pin diodes, implementing distributed load, using ferrite substrate [18][19][20], are also applied to RCSR of antennas successfully.…”

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.
