Summary:
In order to solve the conflict between radar cross section (RCS) reduction and performance of microstrip antenna, bionics principle is applied to antenna, and a bionic butterfly microstrip antenna is presented in this letter. This structure is cutting the fuscous area of butterfly wings in the sunshine away based on bow-tie patch. Simulation and measured results and analysis demonstrate that this bionic antenna can not only guarantee the antenna radiation performance, but also reduce the RCS of the antenna significantly at frequency range from 4 GHz to 8GHz, the largest reduction is up to 23dBsm.
