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...
