A new antenna structure with broadband and high gain at the millimetre-wave bands is presented. This antenna consists of a conventional patch and a new guard ring resonator. By introducing the guard ring resonator, the propagation of the surface wave is prevented, and antenna gain is increased. Furthermore, the bandwidth of this antenna becomes wider due to the coupling of the guard ring resonator with the main patch resonator. The simulated results of the proposed antenna show a bandwidth and peak antenna gain at 60 GHz of 7GHz and 9.6 dBi, respectively.
