Abstract
The previously reported procedure to hybridize the high-band folded transmitarray antenna (FTA) and the low-band Fabry-Perot-cavity-antenna (FPCA) adopts the λ low/2 FPCA as the basic antenna, and the FTA is then integrated with the FPCA. The aperture size and profile of the implemented antenna are highly correlated to the λ low, which restricts further profile shrunk and designable λ low under a given aperture size. A novel procedure tackling these issues is proposed. A double-folded FTA (DFFTA) whose profile is 1/4 of the focal length is first adopted as the basic antenna under a given aperture size. Then, an FPCA with an artificial magnetic conductor-loaded ground is integrated with the DFFTA. The aperture size and the profile of the implemented antenna are completely determined by the DFFTA, which has no correlations of the λ low. An aperture-shared dual-band antenna with a lower profile at both operating bands can be designed by this procedure. Further, the λ low can be freely chosen under a given aperture size and profile. An aperture-shared surface offering partial reflection at 3.5 GHz and phase correction at 28 GHz, and an aperture-shared multifunctional ground offering polarization conversion at 28 GHz and phase compensation at 3.5 GHz are proposed to execute the proposed procedure.Description
