Abstract :
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 that compared to the reference antenna, bionic antennas have lower RCS and favorable radiation performances, which demonstrates that the method of applying bionics principle to antenna RCS reduction is valid.
