Abstract

A novel dual frequency microstrip antenna with low radar cross section (RCS) is proposed in thispaper. Compared with the traditional microstrip antenna, the novelmicrostrip antenna loaded complementary split-ring resonators (CSRRs) has a low RCS. The novel and traditional dual-frequency microstrip antennas with the center frequency of 3.4 GHz and 5 GHz are designed and fabricated. The results demonstrate that the monostatic RCS of the proposed antenna has beenwell reduced. The RCS reduction at 5 GHz is as much as 17 dB. Besides,in the case of the φ-polarized incident wave, the RCS reduction can be achieved in the angular ranges of -90°≤θ≤+90° in xoz-plane and yoz-plane. At the same time, the CSRRs cause no obvious deterioration in radiation performance.
