Front metal coating 20 and the back metal coating 21 on the back side 31, both ends connection, the length and branch of each metal backing
The maximum height h of blade 3 (or between second inserted terminal 35,36) is consistent.The horizontal width of front metal coating 20 and second is inserted
It is consistent to meet end 35,36 horizontal width d, such as is arranged to 0.8-1mm.Back metal coating 21 includes two inserted terminals are completely covered
35th, 36 end 24,25, and broadening interlude coating 22, the horizontal width of interlude coating 22 be more than two inserted terminals 35,
36 horizontal width d, and it is mainly horizontal-extending to the outside of support chip 3.The maximum length of back metal coating 21 and support chip 3
The maximum height h of (or between first inserted terminal 35,36) is consistent, and the horizontal width of in-between section is than inserted terminal horizontal width d more
Greatly, thus formed overstriking ground connection balun 2.The back metal coating 21 of balun 2 is grounded in step of the both ends compared with overstriking between detail
Shape, intermediate width are more than the front metal coating 20 of ground connection balun 2 and the horizontal width of cathode balun 1.The intermediate width is 3
~5mm.The width at both ends may be configured as that the second top inserted terminal 35 and the second bottom inserted terminal 36 is completely covered.Front metal
Also sector width deposited with ground connection balun front and length are consistent for the width of coating 20.Apply the length in area and the maximum height h of support chip 3
Unanimously (such as 16-19mm).Width is consistent with the width d of inserted terminal 35 (such as 0.8-1mm).
More specifically in example, back metal coating 21 is in the horizontal width at both ends and the level of the second inserted terminal 35,36
Equivalent width, interlude 22 (being sandwiched between 3 top margin 32 of support chip and base 33) are that horizontal extension forms outside extension laterally
Metal backing.Its height and the maximum height h of support chip 3 (or between second inserted terminal 35,36) are small.Further, back-side gold
The interlude for belonging to coating 21 extends extend much smaller horizontal width compared with outside inwardly, forms inner side drawn metal coating.Cause
For this back metal coating 21 in middle to the step-like of both sides extension, interlude overall width is larger.Intermediate width is 3~5mm.
In the malen electricity structure 100 of the utility model, effective height for reducing support chip 3, the height of its respective antenna unit,
By varying the feed of cathode balun 1, subtract and carefully shorten balanced feeding, optimize its performance more preferable；At the same time balun 2 is grounded to shorten
Widen balanced feeding, optimize its performance more preferable.
