Abstract

A broadband dual-polarized dipole antenna with overlapped dipole arms is proposed in this paper. To obtain a compact radiator size, the arm-overlapped dipole antenna is constituted by splitting and overlapping the edges of a cross loop dipole. Then four open pins are soldered to the dipole to excite a third resonance at high frequency band. Measured results show that the proposed antenna with a small radiator size of 49×49 mm² has an impedance bandwidth of 49.5% (1.7-2.82 GHz) for VSWR<1.5, port isolation >28 dB and half-power beamwidth (HPBW) of 65º±5º. A 4-element antenna array with 8º±2º electrical down tilt is shown to further validate the performance of the antenna.
