Description
[technical field]
The invention belongs to communication technique fields, more particularly to a kind of high frequency antenna for mobile phone.
[background technique]
Since existing market is very high to mobile phone performance requirement, especially when holding, there are many antenna performance decline, cause
For user when making a phone call or using data service, aerial signal is very poor, it is easy to fall net and call drop.Existing antenna scheme is
One Low Medium Frequency antenna adds a high frequency antenna, if it is only one high frequency antenna, no matter it is placed on mobile phone bottom
If the either right side of left side, mobile phone left and right holding always under holding state, which has holding antenna performance on one side, can deteriorate sternly
Weight.
[summary of the invention]
The main purpose of the present invention is to provide a kind of high frequency antenna for mobile phone, carry out left and right high frequency antenna according to holding state
Switching, solve the problems, such as antenna performance severe exacerbation under hand grasping state.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of high frequency antenna for mobile phone, is arranged in mobile phone back
Bottom and the second high frequency antenna radiator of the first high frequency antenna radiator, setting of keeping right including the setting that keeps left and it is located at
Between middle low-frequency antenna radiator, the right end of the first high frequency antenna radiator is provided with the first feeding point, and described second is high
The left end of frequency antenna radiator is provided with the second feeding point, and first feeding point, second feeding point are opened by a switching
The radio frequency mouth for closing device and Mobile phone antenna circuit is electrically connected, the converting switch device include switch mouth b, switch mouth c and
The switching port a of switched conductive between the switch mouth b and the switch mouth c, first feeding point and the switch mouth b connect
It connects, second feeding point is connect with the switch mouth c, and the radio frequency mouth is connect with the switching port a, the middle low-frequency antenna
Third feeding point and grounding point are provided on radiator.
Further, the end of the middle low-frequency antenna radiator is arranged in the third feeding point.
Compared with prior art, a kind of beneficial effect of high frequency antenna for mobile phone of the present invention is: being held according to mobile phone
State automatically switches the conducting of left and right high frequency antenna.Specifically, palm is directly by the first high frequency antenna when left hand shakes hands machine
Radiator is held, and causes the first high frequency antenna radiator antenna performance to deteriorate serious, this programme is automatic by converting switch device
High-frequency work antenna is switched to the second high frequency antenna radiator to work, greatly improves left hand and holds antenna performance；When the right hand is held
When mobile phone, palm directly holds the second high frequency antenna radiator, causes antenna performance to deteriorate serious, this programme is opened by switching
High-frequency work antenna is switched to the first high frequency antenna radiator automatically and worked by pass device, and greatly it is linear to hold day for the improvement right hand
Energy, either right-hand man, which side, which is held, can all a good antenna performance, to solve antenna performance under hand grasping state
The problem of severe exacerbation.
[Detailed description of the invention]
Fig. 1 is the structural schematic diagram of the embodiment of the present invention；
Digital representation in figure:
100 high frequency antenna for mobile phone；1 first high frequency antenna radiator；2 second high frequency antenna radiators；Low-frequency antenna spoke in 3
Beam；4 first feeding points；5 second feeding points；6 converting switch devices；7 radio frequency mouths；8 third feeding points；9 grounding points.
[specific embodiment]
Embodiment:
Fig. 1 is please referred to, the present embodiment is high frequency antenna for mobile phone 100, is arranged in mobile phone back bottom and sets including keeping left
The the first high frequency antenna radiator 1 set, setting of keeping right the second high frequency antenna radiator 2 and be located in the middle middle low-frequency antenna
Radiator 3, the right end of the first high frequency antenna radiator 1 are provided with the first feeding point 4, the left end of the second high frequency antenna radiator 2
It is provided with the second feeding point 5, the first feeding point 4, the second feeding point 5 pass through a converting switch device 6 and Mobile phone antenna circuit
Radio frequency mouth 7 is electrically connected, and converting switch device 6 includes switch mouth b, switch mouth c and cuts between switch mouth b and switch mouth c
Change the switching port a of conducting, the first feeding point 4 connect with switch mouth b, and the second feeding point 5 is connect with mouth c is switched, radio frequency mouth 7 with cut
A mouthful a connection is changed, is provided with third feeding point 8 and grounding point 9 on middle low-frequency antenna radiator 3.
The end of middle low-frequency antenna radiator 3 is arranged in third feeding point 8.
The working frequency range of the first high frequency antenna radiator 1 and the second high frequency antenna radiator 2 is 2300 in the present embodiment
~2700MHz；The working frequency range of middle low-frequency antenna radiator 3 is 824~960MHz and 1710~2170MHz.
It is switched between two high frequency antennas in left and right by converting switch device 6, realizes two high frequency antennas in left and right
Alternation.
The state that the present embodiment is held according to mobile phone automatically switches the conducting of left and right high frequency antenna.Specifically, working as left hand
Shake hands machine when, palm directly holds the first high frequency antenna radiator 1, cause 1 antenna performance of the first high frequency antenna radiator dislike
Change seriously, high-frequency work antenna is switched to the second high frequency antenna radiator 2 automatically by converting switch device 6 and carries out work by this programme
Make, greatly improves left hand and hold antenna performance；When the right hand shakes hands machine, palm directly holds the second high frequency antenna radiator 2, leads
Antenna performance is caused to deteriorate serious, high-frequency work antenna is switched to the first high frequency antenna automatically by converting switch device 6 by this programme
Radiator 1 works, and greatly improves the right hand and holds antenna performance, either right-hand man, which side, which is held, can all a good day
Linearly energy, to solve the problems, such as antenna performance severe exacerbation under hand grasping state.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
