Description

technical field [0001] The invention relates to the field of antenna design, in particular to a circular polarization probe antenna structure. Background technique [0002] Probe antennas are mainly used in test sites for wireless products, such as near-field test systems, to calibrate the performance of the antenna under test, including gain, near-field amplitude and phase, pattern, sidelobe level, polarization purity, etc. . In the near-field test, the probe antenna is usually required to have small size, high gain, and convenient installation. It is difficult for conventional probe antennas to meet the above requirements at the same time. Contents of the invention [0003] The purpose of the present invention is to provide a miniaturized circularly polarized probe antenna with convenient use, simple installation, low cost and high gain for the special requirements of near-field testing. [0004] In order to achieve the above object, the technical scheme adopted in the...
