A compact and wideband slot antenna backed by a square substrate integrated waveguide (SIW) cavity is presented. By exciting the dual-slotted SIW cavity with an offset coaxial feed, a transverse electric (TE)(110) resonant mode along with two hybrid modes as combinations of TE110 and TE120 resonances can be generated within a close range. The triple resonances contribute to producing a wideband response while maintaining a compact antenna structure. An antenna prototype with a total size of 0.49 lambda(0) x 0.49 lambda(0) x 0.16 lambda(0) is manufactured and experimentally tested. Measures results show that an operating band of about 33.0% is obtained. Meanwhile, it also exhibits stable unidirectional patterns and moderate gains over the whole band.
