Abstract

Directed at eliminating the repeated experiment as required by the conventional method, this paper starts with the design of the Vivaldi UWB antenna of microstrip feed structure. The paper goes to introduce the design of the parts of feed structure by equivalent circuit method, the optimization of the antenna structure by the computer-aided design and the test of prototype of the antenna. This paper ends with an analysis of effect of processing technique on the design parameter. The antenna has a working band of 3.1~10.6 GHz.In this wide band, the antenna gives gain of above 8.5 dB, a width of 3 dB beam efficiency up to 80%, all of which meet FCC-specified UWB antenna indexes.
