Between volume, ensure preferable antenna performance simultaneously.At present, relatively more on market navigation antenna products simply cover GPS frequency range
Or GPS, GLONASS frequency range, or the frequency range that Beidou II is combined with GPS.Lead greatly it is therefore desirable to be designed to cover four
The GNSS antenna of boat system, takes into account four large satellite navigation system simultaneously, it is achieved the universal navigation that GLONASS shares
Antenna.In view of process variations and applied environment difference, the band requirement that antenna covers is bigger.Civilian GNSS universal navigation sky
Lineman's working frequency is 1559.052-1602.5625 MHz.Bandwidth 43.5105MHz.
Based on the navigation antenna of application mainly uses helical antenna and patch antenna technical at present, they have respective excellent
Shortcoming.
Helical antenna is broad-band antenna, can cover GNSS frequency range, and flat helical antenna size is directly proportional to operation wavelength, because of
This antenna entirety is heavy, volume is relatively big, it is big to take up room, and manufacturing cost is high；Three-dimensional helical antenna longitudinally height is relatively big, section
High, be difficult to conformal, make complexity；It is typically mounted at the outer surface of vehicle, boats and ships, it is difficult to conformal fragile.
Paster antenna has the advantage such as simple in construction, small volume.But use conventional design mode, small-sized in order to realize
Change, typically use high dielectric ceramic, need to use the precious metal such as rare earth material high temperature sintering and gold and silver, complex process cost
Height, lateral dimension the most frequently used for 25*25mm, longitudinally height is 6～10mm.Impedance bandwidth is narrow, generally only 15～
The bandwidth of 20MHz, therefore can not cover all frequency ranges of GNSS simultaneously.
Therefore using helical antenna and patch antenna technical, low cost, miniaturization, broadband are that conflicting design is difficult
Topic, prior art cannot meet low cost, the demand of miniaturization GNSS universal navigation antenna simultaneously.
