In this article, a novel design of compact cavity-backed slot antenna based on substrate integrated waveguide (SIW) technology is presented for dual-frequency communication services. A single layer printed circuit board is applied to implement the proposed antenna. The bowtie-ring slot engraved on the SIW square cavity is excited using two orthogonal microstrip feed lines to operate at two distinct frequencies (6.62 GHz and 11.18 GHz). The proposed antenna allows each of these frequencies to be designed independently. A prototype of the proposed cavity-backed antenna that radiates at both 6.62 GHz and 11.18 GHz is fabricated and measured. The port isolation better than 29.3 dB is achieved by utilizing the transmission zeros (TZs), which are produced due to the orthogonal feed lines,TE(110)mode and coupling between theTE(120)andTE(210)modes. The measured peak gains of the proposed diplexing antenna are 5.77 dBi and 5.81 dBi at lower and upper resonating frequencies, respectively. The proposed dual-frequency antenna exhibits the front-to-back-ratio (FTBR) and cross-polarization level greater than 26 dB and 21 dB, respectively, at both resonating frequencies.
