Problems solved by technology

The antenna uses a microstrip vibrator as a director, so that the beam at the bottom elevation angle has end-fire characteristics and broadens the beam. However, the beam broadening of this antenna is not ideal and only has a width of 100°, and it also only works in circular polarization. The second half of the radiation is large, etc.

Abstract

The invention discloses an arbitrary polarization wide beam patch antenna including a first circuit board and a second circuit board. The first circuit board includes a square metal ring and eight parasitic metal wires. The second circuit board includes a square metal ground board, a radiation paster and four plastic bolts. The antenna provided by the invention can be applied to a satellite communication system and can also be used as an array element of a phase control array antenna. The antenna provided by the invention has advantages of being capable of an arbitrary polarization mode when having the wide beam characteristic; having a low back lobe electric level at the same time; and being simple in structure.

Description

technical field [0001] The invention belongs to the technical field of microwave and millimeter wave passive devices, in particular to a wide beam antenna in microwave and millimeter wave passive devices. Background technique [0002] Patch antenna is a commonly used antenna form in modern wireless communication systems. Because of its low profile, stable performance, easy integration, and low cost, it is widely used in miniaturized receiving terminals, phased array radars, and communication satellites. . In these applications, patch antennas are required to have wide beam characteristics, but the typical 3dB beamwidth of patch antennas is about 90°, which cannot meet the requirements of some applications. For phased array antennas, the beam width of the array elements will directly affect the size of the scanning range. At the same time, in navigation satellite terminal systems such as Beidou / GPS, antennas are required to have hemispherical coverage capabilities, and trad...
