Description

technical field [0001] The invention belongs to the technical field of circularly polarized crossed dipole antennas, in particular to a 50° circularly polarized conical beam antenna with a frequency of 2.15 GHz. Background technique [0002] The cone-beam antenna is a kind of antenna with radial symmetry in lobe pattern and polarization direction. It has no radiation in the normal direction of the aperture, and the maximum radiation direction is on the cone surface with a certain inclination angle to the normal. Cone beams have many applications in electronic systems. For example, in high-performance wireless local area networks, cone beams with an inclination angle of 60° are required; in ground vehicles and satellite communications, cone beams of 30°-70° are required; Conical beams with different frequencies corresponding to different inclination angles are required in mobile communications. With the rapid development of the above application fields, more and more attenti...
