Abstract

An umbrella-shaped planar microstrip patch antenna with defective ground is designed in this paper. The conventional ground of the antenna is replaced by the suitable artificial magnetic conductor (AMC) structures, which is in a defective ground. The AMC structures are the metamaterials which help in reduction of surface waves. The antenna structures are implemented to achieve multiband properties. A spiral artificial magnetic conductor (SAMC) with one arm and four arms is used as ground plane to improve antenna performance. Characteristics like operating bandwidth, antenna gain, and efficiency were analyzed for the proposed antennas. All the proposed antennas operate at frequencies 1.9, 7.3, 17.8, and 25 GHz. The average gain and radiation efficiency are improved by adding rectangular patches in the spiral SAMC ground. The detailed design of the proposed antennas and simulated results obtained using ANSYS HFSS are presented.
