Design of Compact Dual-Polarized Printed-Circuit Antenna for Ultra-Wideband Applications

This paper presents a small printed-circuit antenna, which is well suited for ultra-wideband and dual-polarized applications. By exciting six fundamental-mode resonance frequencies and utilizing their respective harmonics, a broadband operation is achieved covering a frequency range between 4.6 and 13.6 GHz with a VSWR less than 2.2 and a gain better than 2 dBi. The design is verified by commercially available software and measurements
