Abstract

In this letter, the overall size of a dual-band bow-tie slot antenna is reduced by modifying the design of the radiating slot and by extending the feeding coplanar transmission line. In particular, it is shown that by sweeping and rounding the edges of the radiating slots and by extending and terminating the feeding coplanar transmission line with a short circuit, the overall size of the antenna layout can be reduced by 47%. A dual-band prototype antenna is manufactured, and measured results are shown to compare very well with simulated values from two different commercial software packages. This letter presents two new techniques that are beneficial for reducing the overall size of a bow-tie slot antenna .
