Abstract

The design and experimental verification of miniaturized cavity-backed self-triplexing antenna (STA) with high-isolation employing half-mode substrate integrated waveguide (HMSIW) are presented in this work. The proposed STA is constructed by using HMSIW, an Y-shaped slot and three 50Ω feed lines. Three unequal radiating patches are generated by engraving an Y-shaped slot on the top surface of the HMSIW cavity to operate at 3.7/5.0/5.8 GHz for WiMAX/WLAN applications. The proposed STA allows to realize one of the operating band independently by keeping other operating band unaltered and vice-versa. The circuit area of STA is highly miniaturized due to the use of HMSIW cavity and loading of Y-shaped slot. The isolations between three ports are greater than 31 dB. The fabricated STA provides 5.5, 5.92 and 5.93 dBi peak gains at 3.7, 5.0 and 5.8 GHz, respectively. The efficiency of the STA is greater than 92% at all the frequency bands. The constructed STA has a front-to-back ratio of more than 23 dB and a separation of more than 21 dB between co-to-cross polarization levels. Fabrication and measurement are used to validate the intended STA.

Keywords: antenna; HMSIW; self-triplexing; Y-shaped slot
