Bow-tie wide-band monopole antenna with the novel impedance-matching technique

摘要

A staircase bow-tie monopole-type antenna that features a novel broadband technique is investigated experimentally and numerically. A bandwidth of 77.1% (VSWR≤2) can be achieved, and an omnidirectional radiation pattern is obtained. The electrical characteristics of the proposed antenna make it attractive for use in multiband mobile systems.
