Abstract

The fusion of dipole and patch antennas is proposed to achieve a wide band and a low profile. By loading parasitic elements, the hybrid modes of dipole and patch are excited simultaneously with the same feeding and shared aperture. Employing a double-layer-metal artificial magnetic conductor (AMC) to replace PEC as the reflector, the height is reduced from 22.5 mm (0.165 λ at 2.2 GHz) to 17.5 mm (0.128 λ ). Two shorting pins are loaded between the radiator and the reflector ground to improve the isolation within the whole band. A prototype of the proposed antenna with double-layer AMC is fabricated and measured. The measured results show that the proposed antenna has a wide impedance bandwidth of 1.68–2.84 GHz (1.16 GHz, 51.3%) and high isolation of more than 25.5 dB. In addition, a stable gain of 8.8 ± 0.2 dBi and a stable radiation pattern with a half-power beamwidth of 59.6 o ± 3.45 o are achieved without any ground walls.
