Description
Technical Field
The utility model relates to an antenna structure designs technical field, specifically is a metal frame antenna structure of high performance.
Background
At present, mobile communication terminal equipment such as mobile phones, tablet computers and the like all adopt metal frame antennas, and the antennas are all full-face screens in the design process, so that the clearance for the antennas is very little, and the antennas are mostly in a clearance environment of 2-4mm, so that the low-frequency efficiency of the antennas is about 20 percent and is approximately-7 db, the low-frequency efficiency is converted into the power of OTA (under the condition of not increasing the power PA), the GSM900 is below 25dbm as a whole, and the LTE BAND 5 is lower than 17 dbm. This performance may affect the customer experience in part.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a metal frame antenna structure of high performance to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a high performance metal bezel antenna structure comprising: PCB board, side frame, underframe, opening, feed point, present the place, supplementary line of walking, side frame and underframe enclose into a rectangle metal frame, and have the opening between the both sides of underframe and the side frame, the PCB board install in the rectangle metal frame that side frame and underframe enclose, the PCB board is connected with the underframe through the feed point respectively and present the place to present the outside that the place is located the feed point, supplementary line of walking set up in the bottom outside of PCB board.
Further, the width of the opening is 1.8 mm.
Furthermore, the distance between the bottom frame and the PCB is 2 mm.
Furthermore, ABS engineering plastics are filled in a gap between the bottom frame and the PCB.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a metal frame antenna structure, the headroom of antenna is 2mm, and antenna low frequency efficiency reaches-5 db, and the contrast tradition design, antenna efficiency promotes 2db, and the cell phone user has better experience, and GSM 900's TRP can reach 27.5dbm, and BHHR/BHHL can reach 20dbm, 16dbm of CMCC standard; the low-frequency radiation of the antenna is completed by the bottom frame, and the middle-high is realized by the auxiliary wiring.
The utility model has the advantages of simple structure, antenna performance are high, improve user experience.
