文摘

A novel dual-mode triple-band communication terminal antenna is proposed in terms of the quadrifilar helix antenna and the BeiDou satellite navigation system. First, the folded arms are introduced, and at the top of the quadrifilar helix antenna, the folded arms are connected to the helix arms by the series capacitors. Second, the above quadrifilar helix antenna is applied to coaxially collocate with an ultrahigh-frequency monopole antenna. Furthermore, to solve the electromagnetic compatibility issues, a sleeve is coaxially collocated around the monopole antenna within the quadrifilar helix antenna, and the sleeve structure dimension parameters are optimized. Third, the above quadrifilar helix antenna collocated with the ultrahigh-frequency sleeve monopole antenna is designed to the B1 and B3 bands, based on the BeiDou satellite navigation system, and the military reserved ultrahigh-frequency communication frequency band is also supported, which satisfies the performance requirements of the multi-function antenna system in the communication terminal of soldier combat system to support navigation service. Finally, some numerical and experiment examples are provided to illustrate the performance of the proposed communication terminal antenna. And it shows that the proposed antenna system can easily be integrated with the existing soldier combat system device which reduced the maintenance costs.
