Abstract

To improve surface current distribution and give dual polarizations, a petal-shaped array antenna with slots was presented. We analyze the surface current of petal-shaped array antenna, study the working modes of each part, and use defect structures to remove surface reverse currents to reduce sidelobes and achieve high gain characteristics. By changing the radiation length of the antenna, the designed antenna operates in the target frequency band. Then, strip defects are introduced to improve surface current and enhance isolation. Finally, antenna prototype was fabricated and measured to demonstrate our ideas. The measured results show that the proposed antenna has a 10 dB impedance bandwidth from 5.74 to 5.82 GHz with a relative bandwidth of 1.4%, and achieves a peak gain of 11.3 dBi at 5.8 GHz. The isolation of the two ports is more than 26.4 dB in the passband. The overall size of the proposed antenna is only 1.47λ₀×1.47λ₀×0.015λ₀.
