Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An antenna structure, comprising:
a rear cover;
a printed circuit board (PCB) configured to support an electronic component;
a PCB floor disposed between the PCB and the rear cover;
a metal frame disposed at edges of the PCB floor and configured to ground the electronic component;
a split antenna formed by a split provided on the metal frame;
a slot antenna formed by a slot connecting the split, wherein the slot is connected to the split on a first side of the slot, and wherein a second side of the slot contacts the PCB floor;
a first feeding network connected to two sides of the split and configured to excite the antenna structure to generate a first radiation mode, wherein a first primary radiator of the first radiation mode is the slot, and wherein a half wavelength in-phase electric field is distributed over the slot;
a second feeding network connected to one side of the split and configured to excite the antenna structure to generate a second radiation mode,
wherein a second primary radiator of the second radiation mode is the PCB floor,
wherein an in-phase current loop is distributed around the slot, and
wherein a first polarization direction of the first radiation mode is orthogonal to a second polarization direction of the second radiation mode.
