Sažetak
This paper reviews not only the characteristic of the linearly-polarized plate-laminated waveguide slot array antenna in the 60 GHz band but also conversion to circular or tilted linear polarization by adding a layer of apertures over the antenna. The linearly-polarized antenna achieves about 80% antenna efficiency and more than 32 dBi of gain is achieved over 4.8 GHz bandwidth. The measured cross-polarization level is well suppressed below −45 dB in the boresite even though the slots are wide. The circularly-polarized 16×16-element array antenna achieves the axial ratio less than 3 dB over 2.5 GHz bandwidth. In the tilted linearly polarized 16 × 16-element array antenna, the measured cross polarization is below −30 dB in the boreside over approximately 5 GHz bandwidth.
