摘要：

A high-gain wideband low-profile open resonator antenna (ORA) is proposed, which consists of a spherical geometry ground and a single layer partially reflective surface (PRS). A PRS with a suitable positive reflection coefficient phase gradient can correct the problem of multiple quasi-Laguerre-Gaussian beam modes that cannot be excited in a first-order height cavity. Combining these two techniques, we dramatically improve the ORA's 3-dB gain bandwidth at a low profile and reduce the antenna sidelobe level. We designed and fabricated this ORA prototype, and the measured results show a 3-dB gain bandwidth of 40% with a peak gain of 18.8 dBi. Our proposed method shows its effectiveness in improving the gain bandwidth of an ORA with a low profile and multiple resonant modes.
