Abstract
The invention discloses a mobile phone antenna. The mobile phone has an all-metal housing and the mobile phone antenna is a slot one arranged on the all-metal housing. According to the mobile phone antenna, regular currents can be excited by two sides of the slot and thus the flow of the regular currents can form effective radiation. Therefore, a resonance point of the antenna can be adjusted by adjusting the length of the slot, so that the antenna has a good transceiving effect and low manufacturing cost.

TMAnd in Europe, normal operating frequency wave band be at 900MHz gsm (GSM) and at the Bluetooth of 2400MHz
TMThe Capability Requirement antenna structure of in these multifrequency wave bands, working can be handled all these frequencies.
Made such as the external antenna structure of telescopic and fixing " short and thick " antenna and to be used for covering the frequency band of being concerned about with a plurality of antenna elements.Yet, because outwardly directed attribute of radio telephone and attribute with frangible structure are compromised than being easier to.
Also have in the prior art and adopt slot antenna, promptly directly in the metal surface grooving realize above-mentioned antenna structure.Such as being quarter-wave open-ended slot antenna.For this slot antenna, the sealing of an end in slit, and the other end is open.The slit is being encouraged by the energy difference of slit excitation port coupling, and excitation port provides positive charge and negative electrical charge near blind end.At existing radio telephone, in mobile communication, can use a more than slot antenna to obtain the radiation in multiband.Yet; Existing slot antenna requires the excitation port and the Tuning mechanism of separating, and slot antenna all is made on the pcb board, because the radiation of antenna for mobile phone needs; Adopt existing this slot antenna; Mobile phone just can't adopt all-metal shell, otherwise full metal jacket will the screened shielded antanna radiation, thereby makes the mobile phone can't normal talking.Thereby, the antenna for mobile phone of the mobile phone of full metal jacket has been proposed new application requirements.
Summary of the invention
The technical problem that the present invention will solve is can't use all-metal shell in order to overcome the prior art antenna for mobile phone; Influence the normal defective of using of mobile phone otherwise will exist; Provide a kind of transmitting-receiving effective, and promote the antenna for mobile phone and the mobile phone thereof of mobile phone metal-like.
The present invention solves above-mentioned technical problem through following technical proposals: a kind of antenna for mobile phone, said mobile phone comprise an all-metal shell, and its characteristics are that said antenna for mobile phone is the slot antenna of being located on the said all-metal shell.
Preferably, said antenna for mobile phone comprises:
One is formed at the slit on the shell of said mobile phone; And
One feed line, said feed line are used to receive the coupling energy that send in said slit.
Preferably, said feed line is formed between the said slit.
Preferably, the length in said slit is 1/4 wavelength.
Preferably, the operating frequency of said antenna for mobile phone is 1800MHz, 900MHz, or 1800MHz and 900MHz.
Preferably, said antenna for mobile phone is located on the metal shell at the said mobile phone back side.
Preferably, said antenna for mobile phone is located on the metal shell of said mobile phone end face.
Preferably, said metal is a copper.
Preferably, described antenna also comprises a radio frequency unit, and said radio frequency unit is electrically connected with said feed line.
Preferably, said radio frequency unit is a radio frequency chip.
The present invention also provides a kind of mobile phone, and its characteristics are, the antenna of said mobile phone is as above any said antenna for mobile phone.
Preferably, said mobile phone is a double frequency mobile phone, and said dual-band mobile phone comprises two antenna for mobile phone that are respectively formed on the said mobile phone metal shell.
Positive progressive effect of the present invention is:
1, antenna for mobile phone of the present invention can be realized the radiation of full metal jacket antenna for mobile phone when radio frequency unit is worked, and can not influence the normal use of mobile phone.
2, antenna for mobile phone of the present invention can inspire regular electric current through the both sides in slit, and the flow of current of rule has promptly formed effective radiation; Therefore, can regulate the resonance point of antenna through the length of regulating the slit, therefore; Not only antenna receiving-sending is effective, and cost of manufacture is low.
3, adopt antenna for mobile phone of the present invention,, therefore can bring the cellphone subscriber magnificent metal-like, promote the good looking appearance degree of mobile phone because the shell of mobile phone is all-metal shell.
