Abstract

The invention discloses a broadband circularly polarized single-arm Archimedes spiral antenna, and relates to the technical field of antennas. The antenna comprises a dielectric plate, a helical antenna single arm is formed on one surface of the dielectric plate, the helical antenna single arm comprises a smooth arc microstrip line located on the inner side and a zigzag microstrip line located onthe outer side, the helical antenna single arm is determined by an Archimedes function as shown in the description, r is the radius of the single-arm helical antenna, [alpha] is the helical constant,[alpha]=0.75 mm / rad, and [phi] is a winding angle; and a smooth arc-shaped microstrip line with the width wa of 2.4 mm rotates from a point O to a point A around the z axis from the origin of coordinates, wherein the winding angle of the point O is as shown in the description, the winding angle of the point A is as shown in the description; a zigzag microstrip line with the winding angle width wm of 3.0 mm at the point A of the winding angle of the point O rotates from the point A to the point B, wherein the winding angle of the point B [phi]m=27[pi], and the antenna has large impedance bandwidth and good radiation characteristics.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a wideband circularly polarized single-arm Archimedes spiral antenna. Background technique [0002] Circularly polarized (CP) antennas are widely used in satellite communication systems. Thanks to the application of circularly polarized antennas, multipath effects can be reduced, and the mismatch between satellites and receiving antennas can be reduced. Among the circularly polarized antennas, the Archimedean helical antenna has received extensive attention because of its high bandwidth, stable half-power beamwidth (HPBW) and good circular polarization characteristics. The traditional Archimedes spiral antenna has two symmetrical antenna arms, which requires a balanced feed to the antenna, which limits its application in engineering. The space occupied by the traditional Archimedes spiral antenna is reduced by half, and the single-arm Archimedes spiral antenna that does not req...
