Abstract

The invention provides a mutual coupling reducible antenna with a probe and patch tangent feeding mode. Four dielectric slabs are laminated and distributed vertically; a floor is positioned below the first dielectric slab; a first radiation patch is positioned on the upper surface of the second dielectric slab; a second radiation patch is positioned on the upper surface of the third dielectric slab; a probe penetrates through the floor and the first dielectric slab; a circular surface at the top end of the probe is positioned on the upper surface of the first dielectric slab; a rectangular patch is positioned on the upper surface of the first dielectric slab; two metal walls are symmetrically distributed on the opposite face of the long side of the radiation patch of the antenna; two radiation patch units and the floor are in parallel; symmetry axes of the two radiation patch units and the floor are superposed; and the probe is tangent with the long side of the rectangular patch. According to the antenna, a close coupling feeding mode that the probe is tangent with the patch is adopted to achieve a broad band, a high dielectric constant covering layer and the coupling patch are adopted to achieve a high gain property, and the metal walls are adopted to reduce mutual coupling between antenna units.

Description

technical field [0001] The invention relates to a communication antenna, in particular to an antenna unit that can reduce inter-unit coupling and can be applied to a millimeter wave band phased array antenna. Background technique [0002] Due to the development of radio communication equipment and electronic information equipment towards multi-function, miniaturization, ultra-wideband, frequency upshift, and friendly coordination with the surrounding environment, this makes broadband, miniaturization, high-gain, and millimeter-wave antennas become domestic and foreign One of the hot topics of research. It involves the broadband impedance matching technology of the antenna, the loading technology of the antenna, the reactance compensation technology of the antenna and other advanced technologies and processes. [0003] In recent years, with the vigorous development of the wireless communication industry and the increase of communication capacity, the frequency band of the an...
