摘要：
A dual-band low-profile substrate integrated waveguide (SIW) dual-dumbbell-shaped-slot-fed (DDSSF) patch antenna is presented in this letter. The antenna is designed using the dual-dumbbell-slot feeding structure in SIW and two patches to radiate. And it achieves two passbands by exciting two modes of dual dumbbell-shaped slots (DDSSs). The first impedance bandwidth is 4.1%, the second one is 10.0% and gains up to 6.7 dBi and 7.4 dBi, respectively. Furthermore, the two bands can be separated from each other and the cross-polarization level is below -30 dB. The simulation and measurement results of the proposed antenna are in good agreements.
