A novel antenna array based on half mode substrate integrated waveguide

A novel half-mode substrate integrated waveguide (HMSIW) leaky-wave antenna array operating at Ku-band is designed and developed in this paper based on the newly proposed guiding wave structure. This antenna array is accurately simulated by using a full-wave electromagnetic simulator and then fabricated through a single-layer printed circuit board (PCB) process. Three different types of this antenna array with slots are simulated and measured in this paper, measured results are in good agreement with simulated results. The proposed antenna is therefore a good candidate for millimeter-wave applications.
