The invention discloses a high-gain low-profile GPS solar cell antenna that adopts slot mode excitation, belongs to the technical field of solar cell antennas, and includes: a dielectric plate, a radiation body and a feed structure; it is characterized in that the radiation body and the feed structure are located at On both sides of the dielectric board, the radiation body is composed of 5 strings of solar cells, which are excited by slot mode. The 5 strings of solar cells are arranged in parallel to form four "H"-shaped excitation slots, and the excitation feeder adopts a split-four The power dividing network of , simultaneously feeds the excitation slots, and the low-pass filter is coplanar with the feeder. The present invention utilizes four gaps between five strings of solar battery strings for excitation design to realize high-gain radiation performance, simultaneously reduces the section height of the antenna, and simplifies the structural design of the antenna. The GPS solar battery antenna can achieve the purpose of communicating with devices requiring high gain, and is suitable for high-gain application environment requirements.
Description
technical field [0001] The invention belongs to the technical field of solar cell antennas, and in particular relates to a high-gain low-profile GPS solar cell antenna that adopts slot mode excitation. Background technique [0002] The traditional GPS solar cell antenna adopts a layered structure design. The solar cell sheet as the radiation body is placed above the feed layer, and the feed line and the floor of the feed point layer are located on both sides of the lower dielectric board. [0003] Although this layered structure design can achieve the purpose of using solar cells as the main body of the GPS antenna radiation, the section height of the GPS solar cell antenna designed with this structure is relatively high, which has certain limitations on the actual application range of the GPS solar cell antenna. limit. Contents of the invention [0004] In order to solve the technical problems existing in the known technology, the present invention provides a high-gain l...
