Embodiment Construction

[0030] Such as figure 1 As shown, a 60° cone beam antenna with a frequency of 12 GHz reflects the direction pattern of the circular patch antenna loaded with the ring gap by the reflector to achieve the required angle. It is mainly composed of two different dielectric substrates, the upper and lower parts. The centers of the two substrates are opposite to each other, and the upper part is mainly composed of a circular patch antenna placed in the gap of the loading ring on the surface of the first dielectric substrate, a circular metal pillar that runs through the entire first dielectric substrate, and a The feed source and the metal ground are composed, and the lower part is mainly composed of a microstrip coil placed on the top layer of the second dielectric substrate and a metal ground placed on the bottom layer of the second dielectric substrate.

[0031] Such as figure 2 As shown, in a further embodiment, the feed probe passes through a hole set at the center of the firs...

Description

technical field [0001] The invention belongs to the technical field of cone beam antennas, in particular to a 60° cone beam antenna with a frequency of 12 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 attention has been paid to the research of the cone beam an...
