CPW-fed conformai ESP antenna for vehicular applications

Abstract

Abstract In this work, a new design of a monopole conformal elliptical-shaped patch (ESP) antenna is proposed for vehicular application. The antenna measures 40×60×0.1mm3, designed on the polyimide substrate material. Coplanar Waveguide (CPW) is considered to enhance the bandwidth. The antenna resonates at 4.26GHz, 6.61GHz frequencies, with a bandwidth of 4360MHz (3.35GHz-7.71GHz). The 3D-gains are 4dBi, 4.2dBi for the two resonant frequencies. The radiation characteristics are observed semi-omnidirectional and directional. Bending analysis is also considered to check its compatibility on the vehicular surface. The antenna can be widely used in the field of Vehicular application for its advantages of simple structure, flexibility, and low profile.
