Embodiment

[0020] Such as figure 1 As shown, an inclined elliptical monopole broadband circularly polarized antenna includes a dielectric substrate, and a floor 1 with an arc-shaped edge is printed on the back of the dielectric substrate. In this embodiment, the floor with an arc-shaped edge is specifically an arc on one side The other three sides of the rectangle coincide with the edge of the dielectric substrate, one side of the floor is arc-shaped, and the guiding current is distributed along the arc.

[0021] The front side of the dielectric substrate is printed with a bent-shaped feeder 2 and an elliptical monopole 3. The bent-shaped feeder is composed of three branches, two of which are respectively perpendicular to the two ends of a branch and facing opposite , the upward-facing branch is connected to the elliptical monopole, and its connection point is close to the left edge of the dielectric substrate, and the downward-facing branch is connected to the edge of the dielectric sub...

Abstract

The invention discloses a tilted elliptical monopole broadband circular polarized antenna, which comprises a dielectric substrate, a back surface of the dielectric substrate is printed with a floor with an arc edge, a front surface of the dielectric substrate is printed with a bent feeder and an elliptical monopole, the elliptical monopole is connected with the bent feeder and the connection point of which is close to one side edge of the dielectric substrate, and the elliptical monopole is inclined to the vertical center line of the dielectric substrate. The circular polarized antenna has the advantages of simple structure, easy manufacture, wide band, small size and easy adjustment.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an inclined elliptical monopole broadband circularly polarized antenna. Background technique [0002] In recent years, with the rapid development of personal and commercial wireless communication systems, the demand for communication equipment such as antennas, couplers, filters, and power splitters has greatly increased. In a wireless communication system, the positions of the transmitting antenna and the receiving antenna are not fixed, and their working efficiency is affected by the environment. Circular polarization technology can avoid the polarization mismatch and multipath scattering of transmitting antenna and receiving antenna. Linearly polarized waves are prone to polarization deflection and attenuation in the transmission environment, while circularly polarized waves will reverse when encountering obstacles. Anti-interference ability and anti-rain and fog ability, and are wid...
