An Ultra-Wideband Coplanar Waveguide Antenna Covering Multiple Frequency Bands
This paper proposes a miniaturized ultra-wideband antenna with multi-mode operation, designed with a coplanar waveguide (CPW) feed to achieve compact dimensions. The antenna's bandwidth is significantly enhanced by using the integration of stubs and strategic cutouts, while circular polarization is introduced to improve transmission and reception performance. Notably, the antenna supports Global Positioning System (GPS), with its right-hand circular polarization (RHCP) meeting satellite positioning requirements. The proposed design achieves an impedance bandwidth of 1.08 GHz to 2.62 GHz (|S<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</inf>| ⩽-6 dB, 84.86%) and an axial ratio (AR) bandwidth (AR<3 dB) from 1.5 GHz to 2.27 GHz (40.84%). With the characteristics of a low profile, high gain, wide bandwidth, and high radiation efficiency, this antenna is well-suited for applications in GPS positioning, satellite communication, LTE and WiFi frequency bands.
