Abstract

The invention discloses a broadband slot dipole antenna. The structure of the antenna is jointly formed by an antenna housing, a mounting plate, a slot dipole, a feeder panel and a radio-frequency connector. By arranging a rectangular metal conductor slot dipole structure which is slotted in a central symmetry mode, the slot dipole and the mounting plate are perpendicularly fastened; the feeder panel is a composite substrate, wherein a special-shaped metal printed circuit is photo-etched on one face of the composite substrate, and the light panel face of the feeder panel is orthogonal and attached to the slot dipole at the biasing position; and the radio-frequency connector is fastened to the back face of the mounting plate, and a probe of the radio-frequency connector penetrates through the mounting plate to be connected with one end of the printed circuit of the feeder panel. The antenna can effectively overcome the defects of pattern interference, narrow bandwidth, low elevation angle and low gain of an existing telemetry system antenna, has the good structure strength and is particularly suitable for a telemetry system on an aircraft.

Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a broadband slot dipole antenna. Background technique [0002] In principle, communication and radar electronic systems are the process of transmitting and receiving electromagnetic waves, and their structures include antennas, transmitters, receivers, signal processors, etc. The communication frequency in the system is limited by the bandwidth of the antenna. If the bandwidth of the antenna is exceeded, the pattern of the antenna will deteriorate and the performance will decrease, which will adversely affect the communication quality. [0003] In order to assess the performance parameters of the aircraft to be measured in the aerospace radar system, it is necessary to download the parameters of the target to be measured during the flight process to the ground telemetry integrated stations distributed on both sides of the flight track in real time through the telemet...
