摘要:Novel designs of planar aperture antenna array are proposed in this paper, which achieve dual-polarized and high-gain performances in 60GHz unlicensed band. In order to achieve high gain, the original planar aperture antenna is expanded to its two-dimensional array form, and the two linear polarizations share the same apertures. The two polarizations are realized by using orthogonal coupling slots excited by substrate-integrated waveguide (SIW) power dividers below. Two array prototypes with 8*8 and 16*16 radiation cells are designed and manufactured based on low-temperature co-fired ceramic (LTCC) technology for ease of integration. Simulated results show the two antennas have -10dB impedance bandwidth and 3dB gain bandwidth of 57.5 – 65GHz and 57 – 64GHz, respectively, with stable, no-squint and symmetrical beams in band, which is verified by measurements. Compared with other reported high-gain and dual-polarized millimeter-wave antennas, the proposed antennas feature low profile, simple structure while keeping high aperture efficiency. The proposed antennas are very suitable for integration and promising in 60GHz short-range communication applications.
