In this letter, a deca-band substrate-integrated waveguide (SIW) antenna with filtering function is proposed. The number of slots was increased from 4 to 10, and the quad-band antenna design is extended to a deca-band antenna. At this time, good impedance matching characteristics are maintained without changing other parameters except the patch length. The fabricated deca-band antenna has 10 resonances between 3–4.4 GHz and a broadside radiation pattern characteristic at each resonance frequency, and the measured gain is 1.8–4.2 dBi.
