Abstract
In this paper, we investigate a low-scattering antenna array consisting of two different low radar cross-section (RCS) antenna elements. The low-scattering performance is achieved by broadband in-band absorbing with x (TM)-polarization and phase cancellation with y (TE)-polarization at normal incidence and a special shape design at grazing incidence. We demonstrate the effectiveness of the proposed antenna array through simulations and measurements. Compared with the reference one, the results show that it can achieve remarkable wideband monostatic RCS reduction from 3.3 to 8 GHz with a maximum reduction value of 23.5 dB at normal incidence and from 4.4 to 12.5 GHz with a peak reduction value of 15.3 dB at grazing incidence. Moreover, a low-RCS carrier is codesigned with the antenna array to verify the low-scattering property, which indicates that the proposed antenna array has a great potential for use in various application scenarios.
