Embodiment Construction
[0030] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0031] The invention implements decoupling and matching network design for the three-element dipole tightly coupled array antenna by adding a planar quasi-Yagi antenna structure. According to the traditional Yagi antenna, a Yagi antenna suitable for PCB (Printed Circuit Board, printed circuit board) structure is designed, also called planar quasi-Yagi antenna. The difference between it and the traditional Yagi antenna is that the antenna integrates all structures On a dielectric substrate with a high dielectric constant, for example, the material of the dielectric substrate in the present invention is Rogers430, the dielectric constant of this material is 3.66, the dielectric loss tangent is tanδ=0.004, and the thickness of the dielectric s...
