Abstract
This paper presents a planar circular patch antenna with high gain and sidelobe suppression working in X-band. Two circular slots are employed in this work to increase gain and SLL, by using the superposition of the field radiated from these apertures. A circle of N = 10 small vias with nonuniform radius load the antenna cavity in order to excite an additional mode and increase the impedance bandwidth. This antenna shows a realized gain of 15 dBi and an SLL of about -14 dB with a relative impedance bandwidth of 4.5% at expenses of an increased area of the antenna. The benefits and limitations of adding more than one radiating aperture are discussed in this paper.
