Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides detailed implementation and specific operation instructions, but the scope of protection of the present invention is not limited to the present invention. Example.

[0029] Such as Figure 1-Figure 4 As shown, a small wide-beam dual-polarized microstrip antenna includes a radiating substrate 1 and a feeding network substrate 3 embedded in a supporting frame 2 , and the radiating substrate 1 is located on the top of the feeding network substrate 3 .

[0030] The base material of the radiating substrate 1 is a dielectric substrate, which is manufactured by printed circuit technology. The radiating substrate 1 is attached with four discrete micro-radiating sheets 101 and a number of soldering sheets 102. Specifically, a micro-radiating sheet 102 with a side length of 0.1λ-0.12λ can be us...

Abstract

The invention discloses a small wide-beam dual-polarized microstrip antenna, which comprises a radiation substrate with four miniature radiation pieces attached and a feed network substrate embedded in a supporting frame, and the radiation substrate is located on the top of the feed network substrate ; There are two intersecting feeder wires on the feeder network substrate, and a metal base plate is attached to the bottom surface, and the crossing parts of the feeder wires are connected by a bridge element; a feeder probe is connected between each micro-radiating sheet and the feeder wires, and A short-circuit column is connected between each micro-radiating sheet and the metal base plate; in addition, a support column is located between the radiation base plate and the feed network base plate, and its two ends are respectively connected to the radiation base plate and the feed network base plate; one side of the bottom surface of the metal base plate There are radio frequency connectors, which are respectively connected to the feeders on the two cross feeders. The invention simultaneously realizes the miniaturization, wide beam and dual polarization characteristics of the microstrip antenna.

Description

technical field [0001] The invention relates to a small-sized wide-beam dual-polarized microstrip antenna, in particular to a small-sized dual-polarized antenna terminal used as a mobile carrier. Background technique [0002] A dual-polarized antenna can transmit or receive two orthogonally polarized electromagnetic waves, so within the same frequency band, the antenna can simultaneously transmit or receive two signals. Therefore, one pair of antennas can realize the function of two antennas, which can reduce the antenna cost and installation space; at the same time, the use of orthogonal polarization for the transceiver antennas can reduce the mutual coupling effect between the transceiver antennas and improve the communication quality; when the transceiver antennas work at the same time It can also expand the communication link and increase the communication capacity. [0003] Commonly used dual-polarized antenna forms include orthogonal half-wave dipole antennas and dual...
