This letter proposes a wideband substrate integrated waveguide (SIW) stacked patch antenna for millimeter‐wave application. The proposed antenna is composed of strip‐line, coupling slot, hollow‐cavity, and stacked patches. Four near‐resonant‐frequency bands can be generated simultaneously to achieve 36% measured fractional impedance bandwidth from 26.5 to 38.2 GHz with the reference of |S11| less than −10 dB, and also with high linear polarization purity. A prototype of the antenna is fabricated and tested to verify the design concept. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2429–2433, 2016
