Abstract

The paper presents a novel design for an ultra wideband antenna which operates from 2.8-11.8 GHz, covering the entire ultra wide band (UWB) frequency range of 3.1 to 10.6 GHz, as approved by FCC. The antenna is in the form of a goblet (chalice) with a partial ground plane. In the paper, antenna design and geometry is described in detail. Hybrid design technique is applied to a simplified circular patch design and final shape of goblet is reached that exhibits ultra-wideband characteristics. Simulated results of different antenna parameters such as return loss (S (1, 1)), VSWR (Voltage Standing Wave Ratio), gain and far-field plots are presented. The measured return loss agrees with the simulated value, which confirms the working of the antenna. This antenna has primarily been designed to be used as part of a medical imaging system, but due to the high bandwidth, compact size and low profile, it promises to be used for various UWB applications.
