摘要：
A low-profile broadband array antenna, which is designed for millimeter-wave (mmW) communications, is proposed in this paper. A one-to-eight way power divider excites the array antenna, which adopts substrate integrated waveguide (SIW) transmission line. The array elements are eight dual-elliptical models. A coupling slot on the SIW is etched to feed the radiators. Simulated results claim that the proposed array antenna achieves an S-11 < -10 dB bandwidth of 32.5 35.0 GHz and a gain of 15.7 dBi at 34GHz. In addition to the far-field radiation characteristics and convenient processing, the array antenna is especially suitable for applications of mmW communications.
