Abstract

An ultra-wideband differential-fed magneto-electric dipole antenna with unidirectional radiation patterns is proposed in this paper. A novel parallel twin-L shaped differential feeding structure provides an ultra-wideband impedance matching. A unified gain can be realized by the modification of the magneto-electric dipole and using a rectangular cavity, instead of a normal ground plane. The antenna can achieve an impedance bandwidth 111.4% for VSWR<;2, stable gain of around 9dbi and a stable radiation pattern for whole operating frequency band. The low-profile small-size antenna(60mm×60mm×15mm) is constructed easily by using PCB fabrication technique.
