Abstract :
A broadband and high gain 4-elements Ka-band tapered slot antenna (TSA) array with an EBG feeding network is presented. The EBG feeding structure is designed to suppress the surface waves causing unbalanced power division and undesired mutual coupling between the output ports. The array design parameters are tuned to achieve a 20 dB gain at 30 GHz, and an impedance bandwidth covers the entire ka-band. The array exhibits a constant gain and a stable radiation pattern over the operating band which makes it suitable for millimeter-wave short distance wireless communications and imaging applications.
