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 miniature wide beam dual polarization microstrip antenna comprising a radiation substrate with four miniature radiation sheets and a feed network substrate nested in a support frame; the radiation substrate is arranged on the top of the feed network substrate; the feed network substrate is provided with two intersected feeders, the bottom face is provided with a metal base board, and the intersected positions of the feeders are connected through a bridge element; a feed probe is connected between each miniature radiation sheet and the feeder, and a short circuit rod is connected between each miniature radiation sheet and the metal base board; in addition, a support rod is arranged between the radiation substrate and the feed network substrate, and two ends of the support rod are connected with the radiation substrate and the feed network substrate respectively; one side of the bottom face of the metal base board is provided with a radio frequency joint connected with the feed portions of two intersected feeders. The miniature wide beam dual polarization microstrip antenna realizes miniature, wide beam, and dual polarization features.

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...
