Description

Mainboard structure and equipment provided with microstrip antenna Technical Field The utility model belongs to the technical field of radio frequency and antennas, and particularly relates to a main board structure provided with a microstrip antenna and equipment. Background The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. When in practical use, the microstrip antenna is often required to be arranged on the main board so as to meet the requirements of receiving and transmitting wireless signals and ensure the normal network communication of equipment, and when in specific application, the reflecting plate is often required to be added so as to further improve the gain and the directivity ‌ of the antenna. The prior microstrip antenna, the connecting mode of the reflecting plate and the main board mainly comprises two modes, wherein the first mode is that the main board adopts a single-sided cloth piece, one side close to the antenna is used as an antenna reflecting plate, the microstrip antenna is arranged on a through hole bonding pad of the main board in a welding mode, the other mode is that the antenna is fixedly connected with the reflecting plate through a screw, and an antenna feed point and a grounding end are led out through a coaxial line and are connected with the main board through the coaxial line. The first mode has the advantages of simple assembly and low cost, but because one side of the main board is used as the reflecting plate, the connecting mode is only suitable for a single-sided cloth main board, and if the connecting mode is used for a double-sided cloth main board, the problem that the reflecting plate is incomplete and the distance between the reflecting plate and the antenna is suddenly changed exists, so that the antenna performance is reduced. In addition, if the reflection surface is provided with a high-speed signal wire, a clock wire or other components such as a switching power supply, weak signals can be amplified by the antenna, so that electromagnetic interference risks are caused, communication quality is affected, and the application range is narrow. The second mode has the advantages of not being limited by single-sided wiring or double-sided wiring of the main board, but the coaxial line connection needs to be connected by adopting an opening wire welding mode on the antenna side, an opening wire welding mode on the main board side or an antenna connector mode, and the like, so that the defects of complex antenna manufacturing, high antenna and main board cost and narrow application range are overcome. Disclosure of utility model In order to solve the problems, the utility model provides a main board structure and equipment provided with a microstrip antenna, wherein a single-sided printed circuit board is additionally arranged as a reflecting plate, the reflecting plate is not directly connected with the microstrip antenna, holes are formed in the reflecting plate so as to accommodate pins of the microstrip antenna, the pins penetrate through the reflecting plate and are connected with the main board, the reflecting plate is detachably connected with the main board, the assembly is simple, the manufacturing cost is reduced, and the limitation of the welding type directional microstrip antenna on the single-sided wiring layout of the main board is solved.
