Abstract
The invention discloses a microminiature dual-circularly-polarized microstrip antenna design method, which comprises the steps that an antenna model is created, the antenna model sequentially comprises a patch antenna, an upper-layer medium, an air layer and a lower-layer medium from top to bottom, probe feeding is adopted for the patch antenna through a microstrip line power divider, and a coaxial cable is wrapped in the air layer; according to the method, the established model is optimized, the position of the feeding point of the antenna is optimized, two linear polarization sources with orthogonal polarization are achieved, and therefore the purpose of circular polarization is achieved. And the angle range of the axial ratio lower than 3dB is-48 degrees to 55 degrees, so that a good axial ratio is achieved.
Description
Technical field [0001] The present invention relates to the technical field of microstrip antenna, relating to ultra-small double-circular polarized microstrip antenna design. Background technique [0002] The microstrip antenna has a small size, light weight, low profile, low manufacturing cost, easy to mass production, easy and microstrip line integration, can obtain a single-directional width direction map, easy to achieve dual-band, bipolarization, etc. Function work. These advantages make the microstrip antenna in a wide frequency domain of approximately 100MHz to 100GHz, widely used in satellite communications, radar, remote sensing, guided weapons, and portable radios. [0003] The concept of microstrip antennas has been proposed in 1953, but did not attach importance to the project. There are only some sporadic research in the fifth and 1960s. Real development and practical use in the 1970s. Due to the development of microwave integrated technology, the production of micr...
