Abstract:Broadband slotted circular patch antenna with Defective Ground Structure intended for Ku band satellite communications is presented in this communication. The proposed antenna has a fundamental circular radiating element in which a square ring slot is etched along with a circular slot inside it. The ground is etched with a rhombus ring slot at the center and square slots in the corners. The defective ground provides multiple frequencies of operation and the slots in the radiating element act as filters combini… Show more
