A novel approach to reduce the dual band microstrip antenna Radar Cross Section (RCS) based on Artificial Magnetic Conductors (AMC) is presented in this paper, and making the size of the antenna which works at 5.1 GHz and 7.4 GHz decreases by 47%. The approach taken is to devise a new dual band AMC structure which has the same frequency with this antenna and load on both sides of the radiating patch...
A modified monopole antenna with plate-loads for bandwidth enhancement is proposed in this paper. The modified monopole antenna is designed based on a semicircular-base monopole. Two rectangle plates are attached to its radiating edges to increase the frequency range significantly. Its radiation characteristics including impedance bandwidth, radiation patterns, and gain are simulated and measured...
The planar rectangular split ring resonator is applied to design the printed dipole antenna with a requirement of dual frequency in this paper. A dual-frequency antenna example is given, which works at 1.7 GHz and 4.0 GHz. Any pair of working frequencies can be obtained by the presented technique. The antenna is simulated and fabricated. Its radiation characteristics including impedance bandwidth,...
Bionics principle is applied to antenna radar cross section (RCS) reduction in this paper. Based on a printed circular disc monopole antenna, two novel bionic antennas are proposed by use of two models from animal kingdom and plant kingdom, respectively. Monostatic RCS and ultrawideband related characteristics of the three antennas are simulated, experimentally verified and compared. The results show...
