Abstract

The invention discloses a broadband slot oscillator antenna, which is composed of a radome, a mounting plate, a slot oscillator, a feed plate and a radio frequency connector. Among them, by setting a rectangular metal conductor gap vibrator structure with a central symmetrical slot, the gap vibrator is vertically fastened to the mounting plate, and the feed plate is a composite substrate with a single-sided photolithographic metal printed line with a special shape, and its light plate surface is at the offset position Orthogonal to and attached to the gap oscillator, the RF connector is fastened on the back of the mounting board, and the probe of the RF connector penetrates the mounting board and is connected to one end of the printed line of the feeder board, which can effectively solve the "interference" of the antenna pattern of the existing telemetry system ", narrow bandwidth, and low gain at low elevation angles. At the same time, it has good structural strength, and is especially suitable for telemetry systems on 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...
