Abstract :
This work presents a double-sided parallel-strip line fed ultra-wideband circular monopole antenna. This antenna exhibits a periodic 2:1 VSWR bandwidth from 1.0-9.0 GHz and a continuous 2:1 VSWR bandwidth from 9.5-14.0 GHz. Above 14.0 GHz, the antenna exhibits a mixture of continuous and periodic 2:1 VSWR bandwidths. At 5.0 GHz the antenna radiates an omni-directional beam with a maximum gain of 5.5 dBi, and at 10.0 GHz the antenna radiates a monopulse beam in the end-fire direction with a maximum gain of 6.7 dBi. These measured results confirm the expected values from simulation.
