Embodiment Construction

[0016] Such as Figure 1~6 As shown, a Beidou rod-shaped buoy antenna includes a plurality of antenna units stacked together to form a rod-shaped structure, and the antenna unit includes a dielectric cylinder 1 and a feed network circuit board 2 at the bottom of the dielectric cylinder 1; A plurality of spiral arms 3 are arranged at intervals around the cylinder 1. The dielectric cylinder 1 is made of non-conductive material, and the spiral arm 3 is made of conductive material. The spiral arms 3 are inlaid or etched on the wall of the dielectric cylinder 1, which is beneficial to reduce the weight of the antenna. To meet the lightweight requirements of the buoy terminal; the lower end of each spiral arm 3 is provided with a short-circuit stub 4 and a feed point 5, the feed network circuit board 2 is provided with a grounding plate and a microstrip feeder, and the short-circuit stub at the lower end of the spiral arm 3 4 is welded together with the ground plate on the feed netw...

Abstract

The invention relates to a Beidou pole-rod buoy antenna. The Beidou pole-rod buoy antenna comprises a plurality of antenna units which are overlaid together to form a pole-shaped structure, the antenna units comprise dielectric cylinder bodies and feed network circuit boards positioned on the bottoms of the dielectric cylinder bodies; a plurality of helical arms are arranged on the peripheries of the dielectric cylinder bodies at intervals; a short-circuit branch knot and a feed point are arranged at a lower end of each helical arm; the feed network circuit boards are provided with ground plates and micro-strip feed lines; the short-circuit branch knots at the lower ends of the helical arms are welded together with the ground plates on the feed network circuit boards; and the feed points at the lower ends of the helical arms are welded together with the micro-strip feed lines on the feed network circuit boards. The Beidou pole-rod buoy antenna has the characteristics of wide wave beam, low power consumption, light weight and the like, is stable and reliable in working, and is high in integral radiation performance, so that the problems of large weight and narrow wave beam existing in the conventional buoy terminal antenna are solved.

Description

technical field [0001] The invention relates to a satellite navigation buoy antenna for Beidou first generation L frequency band, S frequency band, Beidou second generation B1 frequency band and GPS L1 frequency band, in particular to a Beidou pole buoy antenna. Background technique [0002] The rapid development of satellite navigation system plays an important role in national security, economic construction and daily life, and is widely used in military, transportation, surveying and mapping, safety monitoring and other fields. Satellite navigation terminal antenna is an indispensable and important part of satellite navigation terminal equipment, and its performance directly affects the performance of the whole machine. Therefore, satellite navigation terminal antenna has important research significance. At present, ceramic patch antennas, which are widely used in navigation terminal equipment, have the characteristics of small size and easy integration, but they are heav...
