Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Fig. 1, the utility model digital TV antenna 1 has a grounding parts 10, this grounding parts 10 shape that is rectangle substantially, its and arranged on left and right sides is along symmetrical first breach 20 and second breach 21 of all inside recessed formation, thereby grounding parts 10 middle parts form a bossing, and grounding parts 10 has one first side along 11 at first breach, 20 places.
Described first side extends upward a junction 12 along 11 places, this connecting portion 12 have one vertical and be connected in first side along 11 radiation taeniae 121 and the end of autoradiolysis taeniae 121 perpendicular to this radiation taeniae 121 and the radiation horizontal stripe 122 that extends to form in the same manner along 11 bearing of trends with first side.Form one first separate slot 13 between the bossing of described radiation taeniae 121 and grounding parts 10.Described radiation horizontal stripe 122 extends horizontal expansion more vertically upward away from radiation taeniae 121 1 ends and forms one first Department of Radiation 14, the vertical width that is formed with second separate slot, 15, the first Departments of Radiation 14 between this first Department of Radiation 14 and the radiation horizontal stripe 122 is greater than the transverse width of radiation taeniae 121 and vertical width of radiation horizontal stripe 122.
Please continue with reference to Fig. 1, first Department of Radiation 14 laterally extends one first connecting portion 16 away from radiation taeniae 121 1 ends, vertical width of this first connecting portion 16 is less than vertical width of first Department of Radiation 14, and described first connecting portion 16 is in laterally extend the second symmetrical Department of Radiation 17 of one and first Department of Radiation 14 away from first Department of Radiation, 14 1 ends.This second Department of Radiation 17 extends horizontal expansion downwards in the lower end edge of contiguous first Department of Radiation, 14 1 ends and forms one second connecting portion 18, is formed with the 3rd symmetrical separate slot 19 of one and second separate slot 15 between this second connecting portion 18 and second Department of Radiation 17.Described second connecting portion 18 is in extend a feeding portion 30 parallel with radiation taeniae 121 downwards away from vertical this second connecting portion 18 of first connecting portion, 16 1 ends.A rectangular-shaped coupling part 31 is protruded to radiation taeniae 121 in these feeding portion 30 middle parts.Feeding portion 30 has a feed side 32, and second breach, 21 positions of grounding parts 10 are stretched in this feed side 32, is in communication with the outside thereby be formed with L-shaped the 4th separate slot 33, the four separate slots 33 between feeding portion 30 and the grounding parts 10.
