Trident Shaped Ultra Wideband Antenna Analysis based on Substrate Permittivity

摘要

A compact planar trident shaped antenna for ultra wideband applications is presented in this paper. The performance characteristics of the current antenna are investigated by using different substrate materials. The proposed antenna satisfies the voltage standing wave ratio requirement of less than 2 in the frequency band of 3 to 12 GHz except two materials. Moreover obtained group delay and transmission characteristics indicate that the proposed antenna has good transient response. Details of proposed antenna design and results are presented and discussed.
