Abstract

An Ultra-Wideband Quad-Ridged Horn Antenna in ultra-wideband communication system is described in which offer unique advantages its own structure characters. Federal Communications Commission (FCC) regulate that the frequency for the UWB technique is from 3.1GHz to 10.6GHz. UWB pulse is generated in a very short time period (sub-nano second). So, it has spectrum below the allowed noise level. This feature makes it possible to be used for high-speed over short distances. Besides, UWB has many other applications such as high resolution penetrating radar, hidden object detection system, EMC experiments, freespace time-domain (FTD) measurement systems and feed for reflectors. By simulation and optimization, the 3.1GHz to 10.6GHz Quad-Ridged Horn Antenna can realize high gain and dual polarization operations, and the operating bandwidth is enough for practical operation. The Quad-Ridged Horn Antenna excited by two orthogonal laid coaxial-lines working at the operation frequency band from 3.1GHz to 10.6GHz is built and simulated with the application of CST Microwave Studio® Software. This project researches some radiate character such as the gain, return loss and etc. Research shows that Quad-Ridged Horn Antenna can get to high gain and dual polarization. Also, it has the similar with the simple horn antenna. These characteristics will make the antenna a widely application in ultra-wideband communication system.
