Abstract：Circular polarization microstrip patch antenna is widely used in the adaptive array system for anti-interference, antenna array system miniaturization is one of the trend, but as a result of anti-interference antenna unit, distribution, and the same frequency coupling between serious, affect the overall performance of antenna array. This paper proposes a combined antenna design, which is a combination of beidou B3&S antenna applied to 8 unit array anti-interference system to verify the effectiveness of the proposed scheme. The antenna works in the 1.268 GHz and 2.492 GHz, chassis size 180 mm diameter, conventional antenna B3 is 35 × 35, epsilon=16, traditional antenna S uses 30 ×30, epsilon=6;this design adopts the form of an integral antenna, using 50×50, epsilon=10 medium plate, a unit at the same time achieves B3 frequency band and S band, spirit and spacing for B3 half wavelength; Compared with the traditional microstrip circularly polarized antenna, B3 antenna and antenna S unibody design not only meets the antenna unit plans need, but also by improving the size and spacing of each unit radiation, improves the antenna elevation gain.
