Abstract

The invention discloses a composite helical antenna precision manufacturing method and a measurement machining device and belongs to the field of communication equipment manufacturing. The invention particularly relates to a precise manufacturing method and a measurement and machining integrated device for an ultra-wideband three-dimensional helical antenna with composite coating. The precise manufacturing method adopts the combination of various machining techniques and is also combined with the laser measurement location technology to finish the precise manufacturing of the three-dimensional helical antenna. A frustum-shaped polymide substrate is adopted, the upper surface and the conical surface of the polymide substrate of the composite helical antenna are subjected to overall copperization, and the photolithography technique, the laser rough machining and the fine milling finish machining are adopted for machining. A high-precision 2D (2-dimensional) displacement sensor is utilized to carry out antenna feature extraction to realize the integration of machining and measurement. The measurement machining device consists of a measurement machining component and a five-axis precise digital control displacement platform. The manufacturing method and the measurement machining device have good machining precision, high efficiency and good flexibility and can be widely applicable to machining various types of communication equipment.

Description

technical field [0001] The invention belongs to the field of communication equipment manufacturing, and in particular relates to a precision manufacturing method and an integrated measurement and processing device for an ultra-broadband three-dimensional helical antenna coated with composite materials. Background technique [0002] Antennas are important components for transmitting and receiving signals. The composite helical antenna usually adopts a three-dimensional combined structure of a dual-arm planar helical antenna and a dual-arm conical helical antenna with broadband characteristics.
