A reconfigurable stacked microstrip patch antenna is proposed. The antenna operates at an upper frequency fu with a broadside pattern, 7.5-dBi right-hand circularly polarized gain, and 15.8% bandwidth. At a lower frequency fl, the antenna operates as a planar inverted-F antenna (7.3% bandwidth and 3.9-dBi peak gain) with the main beam directed close to the(More)
A compact stack antenna consisting of square patch, loop couplers and inset feed line is simulated in this paper. The proposed antenna have a stacked patch antenna with an arrangement of two substrates separated by an air gape, A coupling is provided using square loop structure. The simulation results obtained with stacked structure are discussed and(More)
