For example, the first current path is input from the first feed portion 22 by the first radiating portion 21 via the first link portion 23 of the U099141458 form number A0101 page 10/32 page 0992072103-0 201222975-shaped bridge structure. The energy is coupled to the second radiating portion 34 of the surface 12, causing a current to flow toward the shape & x -'s crest into a turtle-like path, and the energy is lightly emitted (such as the dotted line of the thirteenth figure) ) - 哲_77) ° At the same time, the first current path is also checked in from the first feed portion 22, and the first portion of the "Feng portion 21" is energized by the first joint portion 23 of the U-shaped bridge structure. Guided to the first portion 24, the flow of current also forms an annular path that radiates energy (as in the solid line portion of Fig. 13). And because the length of the first connection portion 23 of the U-bridge architecture is one-half of the wavelength of the antenna operating frequency, the radiation of the second current path is also radiated [0029] and the energy of the second current path is the same as the first current path. The energy has a phase difference of 180 degrees. Therefore, the U-bridge design method can superimpose the radiation amount of the fourth radiant portion 24 to the radiation amount of the second ray portion 34, and also has a multiplication effect. The original generation of array antennas. Further, in the first connection portion 23 and the second connection portion 33 of the present invention, the shape of the first connection portion 23 and the second connection portion 33 is in addition to the U-bridge structure described above. A larger rectangular area is cut off from a polygonal shape in the interior (the U-shaped bridge structure is an embodiment in which the worn inner shape is a small rectangle). The foregoing is only a preferred embodiment of the present invention. It is not intended to limit the scope of the practice of the invention. That is, the equivalent changes and modifications made by the scope of the patent application of the present invention are covered by the scope of the invention.
