Abstract
Background:
With the development of the application of GPS satellite, the requirement
of anti-jamming and integration for navigation receiving terminal is gradually raised. In terms of
anti-jamming performance, because the satellite signal arrives at the ground with weak intensity and
is vulnerable to electromagnetic interference, the positioning results are not available.
Objective:
Therefore, in complex electromagnetic environment, the anti-jamming navigation receiving
terminal is needed, and the interference nulling or beam pointing can be achieved by using multi-
element antenna array with anti-jamming algorithm.
Methods:
Accordingly to requirements, the development trend of navigation receiving terminal is
from single mode to multi-mode and miniaturization. A miniaturized 7-element anti-jamming antenna
array is proposed. It mainly aims at GPS L1 and L2 frequency points. All elements adopt ceramic
substrate microstrip antenna. The array elements adopt laminated design to effectively reduce
the antenna aperture. The spacing between elements at two frequency points is not greater than half
wavelength, which can ensure the back-end anti-jamming algorithm performance, and its performance
and characteristics are verified through related experiments and simulations.
Results:
Anti-jamming algorithm performance, and its performance and characteristics are verified
through related experiments and simulations.
Conclusion:
The designed multi-element antenna can be used in the anti-jamming application.
