Abstract

This article presents the design of the novel duplexing patch antenna built by integrating one (or two) radiation patch with one (three) substrate integrated waveguide cavity (SIWC). The duplexing antenna's I/O ports are in a single-ended form in the single-SIWC case, and the I/O ports can be either a single-ended or a balanced form in the three-SIWC design. In the latter, two radiating patches are used on both sides of the SIWC for the bi-directional radiation. This double patches configuration effectively widens the antenna's radiation coverage by radiating energy into both the front- and back-side half spaces. The broad-side radiation pattern on both the front- and back-side of the SIWC is observed in the double patches design. The duplexing antenna exhibits a very narrow fractional bandwidth (<1.7%) and a guaranteed isolation (>40 dB) between the two duplexing ports in the single-ended I/O case. In the balanced one, the differential (common) mode isolations are larger than 40 (58) dB, and the common mode (CM) return losses, which stand for the quality of CM suppressions, are <0.3 dB.
