The problem of asking.
Optionally, by default between each antenna arm 12 and the spacer 2 nearest apart from the antenna arm 12
Frequency selective network 33 is electrically connected.
Now, network 33 and the different antennae arm 12 of the both sides of breaking joint 11 is selected to be electrically connected by predeterminated frequency, it is real
Showed frequency-division filter, by frequency-division filter extend low-frequency current path (because required current path and working frequency into
It is reversely related), the performance of low frequency function is improved, such as lifting 13.56MHz NFC (the short distance wireless communication technology, Near

As a kind of optional implementation, shown in reference picture 2,3, a spacer is provided with the breaking joint 11
2, the spacer 2 selects network 31 to be grounded by a predeterminated frequency, and selects network 32 to connect by another predeterminated frequency
Connect and be grounded after feed 5.
Here, by inserting spacer 2 in the breaking joint 11 between multiple antennas, and spacer 2 is made to be selected by predeterminated frequency
Network 31 is grounded, i.e., the spacer 2 with frequency selectivity is inserted in the breaking joint 11 between multiple antennas, now 2 pairs of spacer
The antenna of the both sides of breaking joint 11 can have different impedance responses, so as to be lifted while isolation, improving antenna multiple antennas
The free degree of performance adjustment.And the collocation feed 5 of spacer 2 selects network 32 with predeterminated frequency, influence septum primum can reduced from effect
Under fruit, the function of an antenna is reached, and then can reach the design of correspondence MIMO multiple antennas.
Now, it is new to add an antenna feed 5 (such as WiFi 802.11a, 5.15GHz~5.85GHz feed, but be not limited to
This), spacer 2 is connected to via predeterminated frequency selection network 32, selects network 32 to may be such that isolation by designing predeterminated frequency
Piece 2 and the feed 5 newly added are essentially opened a way, and select network 31 to may be such that the feed 5 newly added by designing predeterminated frequency

The function of another new antenna, and combined with other spacers 2, reach correspondence MIMO multiple antenna design.
The above-mentioned terminal multi-antenna structure of the present invention, can do corresponding frequency for the operating frequency of antenna of the both sides of breaking joint 11
Selection design, to cause the impedance load that two antennas are experienced to same spacer 2 different.For example, being selected by predeterminated frequency
The different impedance response of Antenna Design of the network 31 to the both sides of breaking joint 11, making spacer 2, certain side antenna is to connect to breaking joint 11
Nearly short-circuit condition, and be close to open-circuit condition, so as to can have different responses to the antenna of the both sides of breaking joint 11 to opposite side antenna
With influence, therefore there is the higher antenna performance debugging free degree.
Wherein, based on different impedance responses are deliberately designed to the both sides antenna of breaking joint 11, the position that can carry out spacer 2 is excellent
Change, i.e., spacer 2 can be arranged in breaking joint 11 in a centered manner, can not also mode placed in the middle be arranged in breaking joint 11, from
And reach more preferably antenna performance.
Particularly, when short-circuit (ground connection) state is presented to certain side antenna in spacer 2, spacer 2 can be adjusted deviation
This side antenna, i.e., it is close to the antenna that open-circuit condition is presented in opposite side, it is linear to the side day because short-circuit condition is presented to reduce
The influence of energy.And this method can often reduce the demand that increase breaking joint 11 disconnects width, it is ensured that appearance, and there is preferably antenna

This), spacer 2 is connected to via predeterminated frequency selection network 32, selects network 32 to may be such that isolation by designing predeterminated frequency
Piece 2 and the feed 5 newly added are essentially opened a way, and select network 31 to may be such that the feed 5 newly added by designing predeterminated frequency
Open circuit (but not limited to) is also essentially to ground.It is so designed that down, spacer 2 can reach isolation breaking joint both sides antenna, and have concurrently
The function of another new antenna, and combined with other spacers 2, reach correspondence MIMO multiple antenna design.
The above-mentioned terminal multi-antenna structure of the present invention, can do corresponding frequency for the operating frequency of antenna of the both sides of breaking joint 11
Selection design, to cause the impedance load that two antennas are experienced to same spacer 2 different.For example, being selected by predeterminated frequency
The different impedance response of Antenna Design of the network 31 to the both sides of breaking joint 11, making spacer 2, certain side antenna is to connect to breaking joint 11
Nearly short-circuit condition, and be close to open-circuit condition, so as to can have different responses to the antenna of the both sides of breaking joint 11 to opposite side antenna
With influence, therefore there is the higher antenna performance debugging free degree.
Wherein, based on different impedance responses are deliberately designed to the both sides antenna of breaking joint 11, the position that can carry out spacer 2 is excellent
Change, i.e., spacer 2 can be arranged in breaking joint 11 in a centered manner, can not also mode placed in the middle be arranged in breaking joint 11, from
And reach more preferably antenna performance.
Particularly, when short-circuit (ground connection) state is presented to certain side antenna in spacer 2, spacer 2 can be adjusted deviation
This side antenna, i.e., it is close to the antenna that open-circuit condition is presented in opposite side, it is linear to the side day because short-circuit condition is presented to reduce
