The invention provides a dual-polarized antenna and a mobile sensor, and the dual-polarized antenna comprises a first metal layer, a first dielectric layer, a second dielectric layer and a second metal layer which are sequentially stacked. Symmetrical first slotted holes are formed in the first metal layer, and through and symmetrical second slotted holes are formed in the second dielectric layer and the second metal layer; a coupling metal sheet is clamped between the first dielectric layer and the second dielectric layer, the coupling metal sheet is connected with a feed port through a transmission line, and the feed port extends into the second slot and is suspended. The feed port is led to the distance closer to the center of the first metal layer through the transmission line, so that the size of the dual-polarized antenna is reduced, the impedance requirement corresponding to the dual-polarized antenna is met, an installation position is reserved for the radio frequency chip at the center of the second metal layer, the radio frequency chip and the dual-polarized antenna do not influence each other to work, and the antenna performance is improved. And the size of the electronic equipment is integrally reduced.
Description
technical field [0001] The present application belongs to the field of antenna technology, and in particular relates to a dual-polarized antenna and a mobile sensor. Background technique [0002] A motion sensor is a device that changes its shape by sensing the movement of an object. Microstrip patch antennas are generally installed on mobile sensors to transmit or receive electromagnetic waves. Microstrip patch antennas include single-polarized antennas and dual-polarized antennas. [0003] With the development of the times, people are increasingly pursuing electronic devices with smaller size, and the size of the antenna is also smaller. The microstrip antenna generally determines the corresponding input impedance of the microstrip antenna by the off-center position of the feed port. In order to obtain a microstrip antenna with a smaller volume, for a single-polarized antenna, the input impedance corresponding to the microstrip antenna can be obtained by means of slotti...
