Abstract

This article presents a compact, triple-band half mode substrate integrated waveguide (HMSIW) based self-multiplexing antenna (SMA) designed for various X-/Ku- band applications. The proposed SMA comprises a compact HMSIW with slots of unequal widths excited with three different ports resembling the anatomy of an arrow. These three slots are driven by a 50 Ω microstrip line feed, facilitating radiations at 10.82, 12.28, and 13.95 GHz with good isolation between the ports. Independent functioning at three different frequency bands is made possible by the remarkable versatility of the proposed SMA design method. With the isolation of nearly 20 dB between ports and gains of 3.97, 4.62, and 7.55 dBi at ports resonating at three distinct frequencies, the SMA-HMSIW element's total arrangement allows for a small antenna size of 0.44λ_g² at the lowest frequency of operation. The proposed SMA structure has been fabricated, and the results are measured which show good agreement with simulated ones.
