Abstract

The invention discloses a Beidou light and small multi-arm measurement antenna based on FPC flexible materials, which includes a casing and a base mechanism, and also includes a dielectric support body, a first spiral radiator, a second spiral radiator, a grounding plate, and several feeding mechanisms. The base mechanism is arranged on the lower part of the medium support body, the grounding plate is arranged on the upper part of the medium support body, the first spiral radiator and the second spiral radiator are arranged on the upper part of the grounding plate, and the feeding mechanism is evenly distributed in the shape of a ring. Around the floor, the bottom of the shell is detachably connected with the medium support. The present invention is provided with a resonant high-frequency arm 1 and a resonant high-frequency arm 2, which are wound in a spiral shape, which can reduce the volume of the antenna, and at the same time use a low dielectric constant medium support body, which improves the device operating bandwidth and gain.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a Beidou light and small multi-arm measurement type antenna based on FPC flexible materials. Background technique [0002] With the rapid development of Beidou navigation and positioning modules, in order to meet the application requirements of compatible multi-system and multi-frequency GNSS terminal equipment, especially for the current wearable, handheld, UAV and other decimeter-level, centimeter-level, millimeter-level Navigation and positioning terminal module and equipment supporting antenna application requirements, the requirements for the antenna should not only meet the high performance, high efficiency, multi-attitude stable reception, but also the structure should meet the design requirements of light, small, flexible and portable. [0003] The structure of the existing helical antenna is difficult, the cost is high, the assembly is easily deformed, and the overall p...
