Detailed description of the invention
In order to make the technical problem to be solved in the present invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 1, be applied to the double frequency dipole antenna of Netcom's terminal unit in present pre-ferred embodiments, double frequency dipole antenna includes antenna body, and antenna body includes first antenna unit 1 and the second antenna element 2.
First antenna unit 1 includes the first radiant section the 20, second radiant section 10 and the first feeder line 30, and the first radiant section 20 and the second radiant section 10 are positioned at the same side of the first feeder line 30, and is respectively perpendicular Rhizoma Nelumbinis and is connected to the two ends of the first feeder line 30; Second antenna element 2 includes the 3rd radiant section the 11, the 4th radiant section 21 and the second feeder line, second feeder line and the first feeder line 30 are separated by with gap, 3rd radiant section 11 and the 4th radiant section 21 are positioned at the side away from the first feeder line 30 of the second feeder line 31, and are respectively perpendicular Rhizoma Nelumbinis and are connected to the two ends of the second feeder line 31; First feeder line 30 and the second feeder line 31 one of them be provided with earth point 01, another is provided with signal feed-in point 00; First radiant section 20 is staggered relative with the 4th radiant section 21, and both are operated in first antenna frequency; Second radiant section 10 is staggered relative with the 3rd radiant section 11, and both are operated in the second antenna frequencies.
In the present embodiment, the first radiant section 20 and the 4th radiant section 21 electricity are equal sized. Second radiant section 10 and the 3rd radiant section 11 electricity are equal sized, and electricity size refers to the path of radiant section, such as the wiring path on pcb board. First antenna unit 1 and the second antenna element 2 are unsymmetric structure, it is beneficial to the welding of 50 sections of cable lines, within space required for welding is contained in antenna body, assembly space needed for antenna body is little, and although two ends, left and right are asymmetric but electric equal sized, current balance type, visual actually used situation converts.
In one embodiment, the first radiant section 20 and the 4th radiant section 21 are bending type, and the first vertical Rhizoma Nelumbinis in radiant section 20 one end is connected to the first feeder line 30, and the other end bends to the second radiant section 10 direction; The 4th vertical Rhizoma Nelumbinis in radiant section 21 one end is connected to the second feeder line 31, and the other end bends to the 3rd radiant section 11 direction.
