Embodiment 1

[0028] Such as figure 1 and figure 2 As shown, the present invention provides a mobile phone antenna 11, the mobile phone antenna 11 is applied to a mobile phone with a full metal casing 1, and the mobile phone antenna 11 is a slot antenna arranged on the full metal casing 11 of the mobile phone.

[0029] Preferably, the slot antenna of the present invention is composed of a feeder and a slot 111 provided on the metal casing of the mobile phone. Wherein, the feeding line is formed between the slots 111 for receiving the coupled energy sent by the slots 111 . The length of the gap determines the resonant frequency point, and the resonant frequency point should be at the frequency point of the mobile phone, such as 1800MHz / 900MHz.

[0030] Further, the length of the slot 111 is 1 / 4 of the wavelength, and it can also be fine-tuned specifically, that is, the resonance point of the antenna is adjusted by adjusting the length of the slot 111 .

[0031] Preferably, the mobile pho...

Embodiment 2

[0035] Based on the mobile phone antenna above, the present invention also provides a mobile phone using the above mobile phone antenna 11 .

[0036] Further, the mobile phone of the present invention may be a dual-band mobile phone, which includes two mobile phone antennas 11 respectively formed on the metal casing 1 of the mobile phone. One of the antennas is located on the metal case on the back of the phone, and the other antenna is located on the metal case on the top of the phone. The resonant frequencies corresponding to the two mobile phone antennas may be 900MHz / 1800MHz.

[0037] The mobile phone antenna of the present invention can excite regular currents through both sides of the slit, and the flow of regular currents forms effective radiation. Therefore, the resonance point of the antenna can be adjusted by adjusting the length of the slit. Therefore, not only the antenna transmits and receives The effect is good, and the production cost is low.

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.

Description

technical field [0001] The invention relates to a mobile phone antenna and a mobile phone thereof, in particular to a mobile phone antenna with a full metal casing and a mobile phone thereof. Background technique [0002] Today's wireless communications technology requires cellular radiotelephone products to be capable of operating in multiple frequency bands. In the United States, normal operating frequency bands are (for example) Analog, Code Division Multiple Access (CDMA) or Time Division Multiple Access (TDMA) at 800MHz, Global Positioning System (GPS) at 1500MHz, Personal Communications System (PCS) at 1900MHz ), and Bluetooth at 2400MHz TM . In Europe, the normal operating frequency bands are Global System for Mobile Phones (GSM) at 900MHz and Bluetooth at 2400MHz. TM . The ability to operate in these multi-frequency bands requires antenna structures capable of handling all of these frequencies. [0003] External antenna structures such as retractable and fixed "...
