Embodiment Construction
[0021] The present invention provides a three-frequency dual-polarized microstrip antenna. In order to make the objectives, technical solutions and effects of the present invention clearer and clearer, the present invention will be described in further detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0022] Such as figure 1 and 2 As shown, figure 1 Is a top view of the three-band dual-polarized microstrip antenna in an embodiment of the present invention; figure 2 for figure 1 The cross-sectional view at the center A (where A passes through the feed probe 8). The present invention provides a three-frequency dual-polarized microstrip antenna. Specifically, the three-frequency dual-polarized microstrip antenna is sequentially arranged with an upper layer from top to bottom. Microstrip antenna 1, upper dielectric substrate 4, intermediate microstrip antenna 2...

The invention discloses a triple-frequency dual-polarized microstrip antenna, wherein the triple-frequency dual-polarized microstrip antenna is sequentially provided with an upper-layer microstrip antenna, an upper-layer dielectric substrate, a middle-layer microstrip antenna, and a middle-layer microstrip antenna. Dielectric substrate, lower layer microstrip antenna, lower layer dielectric substrate and reflector; wherein, the upper layer microstrip antenna works at GSM 1800 frequency, the middle layer microstrip antenna works at GPS L1 frequency, and the lower layer microstrip antenna Work at GPS L2 frequency; also be provided with a feeding probe connected to the reflector, the feeding probe passes through the lower layer microstrip antenna and the middle layer microstrip antenna, and connects with the upper layer microstrip Antenna connection. The present invention effectively solves the problem that the coexistence of multiple antennas in the prior art will produce mutual coupling and negative effects on the performance of the system, and its structure is simple and easy to implement, so that the prepared triple-frequency dual-polarized microstrip antenna can be Applied to handheld terminal equipment.
Description
Technical field [0001] The invention relates to the field of satellite navigation antennas, in particular to a three-frequency dual-polarization microstrip antenna. Background technique [0002] With the continuous advancement of science and technology, people's demand for using the global positioning system GPS to obtain more accurate time and positioning information continues to increase, thus promoting the research and continuous development of this technical field. For measurement and geographic information applications, most handheld terminals use GPS L1 frequency (1.575 GHz). GPS L1 frequency is also widely used in vehicles. For example, GPS L1 frequency band and GPS L2 frequency band (1.227 GHz) Differential GPS (DGPS) ) The error range of less than 10 cm can be obtained in the measurement system. The integration of GPS L1 and GPS L2 frequency bands with terrestrial wireless communication networks (such as Global System for Mobile Communications) can promote the dissemina...
