摘要：

This paper reports the development of a dual-band slotted waveguide antenna array with orthogonal polarizations for dual-use radars. It can be applied for simultaneously enabling communications and tracking functions. The radiating structure is composed by two groups of slots milled into the waveguide opposite faces, allowing an antenna operation over two different frequency bands. Numerical results obtained using ANSYS HFSS and measurements demonstrate two bandwidths of approximately 11.42% and 3.27% in the Sband and C-band, respectively. The antenna gain varies from 11.12dBi at 2.5Gz to 18.92dBi at 4.9Gz. Experiments of a dual-use 64-QAM OFDM wireless communications at 4.9GHz and radar operation in terms of Doppler measurement of a moving target at 2.5GHz illustrate the applicability of the proposed antenna array.
