Embodiment Construction

[0041] The present invention will be further described below in conjunction with specific embodiments. The following examples are only used to illustrate the technical solutions of the present invention more clearly, rather than to limit the present invention.

[0042] like figure 1 As shown, the ultra-wideband planar antenna array for millimeter wave communication includes the antenna body and the feed network.

[0043] The antenna body is composed of 8×8 antenna elements arranged at equal intervals in the two-dimensional direction, and the interval d=5.4mm.

[0044] like figure 2 As shown, the feed network is a parallel feed network with 1 input and 64 outputs, and the output ports of the feed network have equal amplitudes and phases. The output port of the feed network is connected to the input port of the microstrip feeder 7 .

[0045] like Figure 3-6As shown, the antenna unit includes an E-shaped radiation patch 1 , a first dielectric substrate 3 , an adhesive lay...

Abstract

The invention provides an ultra-wideband planar antenna array applied to a millimeter wave communication system. The planar antenna array is composed of a plurality of antenna units arranged at equal intervals and a microstrip feed network. The antenna unit sequentially comprises a radiation patch, a first dielectric substrate, a bonding layer, a metal ground, a second dielectric substrate and a microstrip feeder line from top to bottom; the radiation patch is connected with the metal ground through four metal holes penetrating through the first dielectric substrate and the bonding layer; according to the design, the antenna unit can work in a dipole mode besides working in a patch mode. In the array environment, due to the mutual coupling effect between the units, another new medium resonance mode is excited at the same time. Therefore, the antenna unit provided by the invention can work in three resonant modes at the same time, so that the planar antenna array can realize ultra-wide working bandwidth, and the radiation in the working band is stable.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to an ultra-wideband planar antenna array applied to a millimeter-wave communication system, which can be used as a receiving and transmitting antenna for a medium- and long-distance millimeter-wave communication system. Background technique [0002] As a component for transmitting and receiving electromagnetic wave energy, antennas are widely used in various communication systems. Due to the advantages of the Sub-6GHz frequency band in wide-area coverage, the spectrum has been widely used in fields including civil mobile communications, and the available frequency band resources, especially large bandwidth resources, are already very limited. The requirements of high-speed and large-capacity communication require large-bandwidth spectrum resources. However, there are a large number of large-bandwidth spectrum resources in the millimeter-wave frequency band, which can be effectively...
