Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] This embodiment provides a TE electromagnetic flying loop generator based on a loop antenna array, and its three-dimensional stereogram is as follows figure 1 As shown, the top view is as figure 2 shown. It includes a circular metal floor, 112 antenna units on the front of the floor, and 112 SMA connectors on the back of the floor. The 112 antenna units are distributed in the shape of concentric rings, placed tangentially and vertically fixed on the metal floor 1, from the center of the circle to the outside are the first ring to the seventh ring, and the corresponding position of the seventh ring is like an electromagnetic flying ring The value of the electric field has dropped below 0.2 of the maximum value. Four identical antenna units 2 are placed in the first ring, and the angular distance between adjacent antenna units 2 is 90°. The an...

The invention discloses an electromagnetic flying ring generator based on a loop antenna array, and belongs to the technical field of microwave antennas. The electromagnetic flying ring generator comprises a circular metal floor, 2N * (N + 1) antenna units arranged on the front surface of the floor, and a coaxial feeder line arranged on the back surface of the floor, wherein the 2N * (N + 1) antenna units are distributed in a concentric ring shape and are respectively the first ring to the Nth ring from the circle center to the outside, 4n antenna units are arranged at the n-th ring (n = 1...N), and the antenna units in the same ring have the same structure and are arranged at equal intervals. According to the method, the annular antenna array is constructed, the antenna array direct radiation mode is adopted, and the electromagnetic flying ring analytic function is selected as an excitation signal; after the excitation signal is radiated out through the antenna array, the excitationsignal can be repaired into the electromagnetic flying ring through the self-repairing characteristic of the electromagnetic flying ring, and implementation of the toroidal topological structure of the electromagnetic flying ring is completed.
Description
technical field [0001] The invention belongs to the technical field of microwave antennas, in particular to an electromagnetic flying loop generator based on a loop antenna array. Background technique [0002] As a finite energy impulse solution of Maxwell's equations, the electromagnetic flying ring has a toroidal topology. The electric field of the TE electromagnetic flying ring is distributed in a ring shape on the cross section perpendicular to the propagation direction, and the magnetic field rotates around the electric field to form a closed loop. The TM electromagnetic flying ring can be obtained by exchanging the positions of the electric field and the magnetic field of the TE electromagnetic flying ring. Flying rings have a strong longitudinal field component on the propagation axis. At the same time, because the wave equation solution of the electromagnetic flying loop is inseparable in space and time, the electromagnetic flying loop has a wide frequency spectrum ...
