There are various receiving antennas of satellite radio
navigation systems. As a rule, the qualitative polarization
characteristics (axial ratio) are achieved by efficiency degradation
or frequency ranges decreasing. In this article, a circular
polarization GNSS antenna, which have no disadvantages described
above are presented. By using a new planar feeding network and a
three layer design of patch elements, it is possible to provide a
symmetrical radiation pattern with high axial ratio and efficiency in
various GNSS frequency bands
L1/L2/L5/G1/G2/G3/E1/E2/E5ab//B1/B2 et al. Moreover, in the
proposed antenna the capacitive caps were used to feed microstrip
patch. It allowed getting good reflection coefficient in the extended
frequency range (~ 10% for one patch element) and receiving of all
GNSS signals by just two resonant elements. In the article, the
breadboarding was carried out and the experimental results of
electrodynamic characteristics were obtained. Perspective
application of the proposed antenna design is demonstrated using
these characteristics. It should be noted that the proposed antenna
has low weight and low manufacturing cost due to the use of
microstrip technology.
