1) it is distributing point when 202, low frequency (880-960MHz) and one section of high frequency (1710-2170MHz) can be produced, 205
Place adds switch (such as single-pole double-throw switch (SPDT)), it is possible to realizes the switching of low frequency, meets 824-960MHz.
The scheme of the embodiment of the present invention, after adding 204, can change resonant frequency and antenna side by fine setting antenna cabling
Tropism, after being simultaneously introduced 202, fine setting can produce other one section of high frequency (2300-2700), and whole scheme realizes the whole network passband section
Demand.
The addition path of 204 and 202 is to print antenna by structural integrity molding or 3D to realize.
2) it is distributing point when 205, low frequency (880-960MHz) and one section of high frequency (1710-2170MHz) can be produced, 202
Place adds switch (such as single-pole double-throw switch (SPDT)), it is achieved the switching of low frequency, meets 824-960MHz.
The embodiment of the present invention is simultaneously introduced 201, can change resonant frequency and antenna directivity by fine setting antenna cabling,
After adding 204, fine setting can produce other one section of high frequency (2300-2700), and whole scheme realizes the whole network passband section demand.
3) when 202 or 205 feed, if whole low frequency covers (824-960MHz), then 205 positions need not add
Switch, with cost-effective.
The embodiment of the present invention is separately added into metal center cabling at breaking joint two ends, it is possible to be effectively improved and cover what the whole network led to
High frequency.
