Abstract :

In recent years many studies are concentrated on UWB microstrip antenna structures for important purposes in wireless communication systems, medical imaging, and radar sensor resolution. In this paper, we printed a spade-shaped radiator patch on nearly rectangular substrate of (30 x 28mm) made of Taconic TLY-5 material. The relative dielectric constant was 2.2, and the thickness of the material was 1.575mm. The patch was fed by a transmission line feeder, and there was a gap between the patch and the ground plane. The computer simulation test (CST) microwave studio software was used in the simulation, and anechoic chamber with a network analyzer was used during the experimental tests. The simulated and measured results demonstrated that the proposed antenna achieved a wide impedance bandwidth from 3.7 GHz to 12 GHz with a return loss of less than -10 dB with a feed gap of 1 mm. The simulated and measured radiation patterns were maintained to be nearly omni-directional radiation characteristics.
