Whole sealing metal frame mobile phone antenna design method adding antenna thickness

The invention discloses a whole sealing metal frame mobile phone antenna design method adding antenna thickness, and relates to the antenna technical field of wireless communication terminal equipment; an antenna radiation body is arranged on the inner surface of a cell cover; a feed source coaxial cable outer conductor is welded on a metal middle plate, so a whole sealing metal housing can become the antenna earth, thus maximizing the thickness between the antenna radiation body and the antenna earth, and maximizing the antenna performance. The metal mobile phone housing can realize well antenna reception and emission performance while allowing the mobile phone to be thinner, thus ensuring the metal frame integrity, and improving user experiences; the antenna earth and the metal middle plate are fixed by the laser welding technology, thus realizing more stable connection; a RF PCB small plate can be omitted, so the antenna pure space can be pourer, thus providing larger communication bandwidth, higher data t
