As an essential base component, the high-precision antenna has an important impact on the quality of the signal. The performance of high-precision antenna is a key factor in determining the performance indicators of satellite navigation terminals. This article proposed small-scalarized antennas for high-precision applications. Toward the flat antenna and cylindrical antenna, the study on the miniaturization of multi-band active circuits is introduced. It solved contradictions between multi-band combination and antenna size miniaturization. Through simulation and analysis, we found a composite radiator is formed by adding the coupling ring around the double layer 3D microstrip antenna. And the stereo radiator is formed, with the coupling ring around the top microstrip antenna linked with the patch surface of the underlying 3D microstrip antenna. Those can effectively broaden the antenna gain of 3 dB beam width (GBW), and axial ratio of 3 dB beam width (ARBW), with increasing the low elevation gain. Accordingly, those antennas can provide good gain properties under smaller dimensions.
