Embodiment Construction

[0041] Traditional handheld devices using MIMO have the problems of signal interference and difficult configuration of planar antennas.

[0042] In contrast, the embodiment of the present invention integrates two planar antennas into one planar antenna, which not only reduces the total headroom of the planar antenna, but also reduces the problem of mutual interference of the planar antennas. Embodiments of the invention will be described in detail below with reference to the accompanying drawings, which illustrate exemplary embodiments of the invention, wherein like reference numerals indicate like or similar elements.

[0043] image 3 is a schematic diagram of two planar antennas according to the first embodiment of the present invention. The antenna part 20 includes a radiation part 201 and an extension part 202 . The extension part 202 extends outward from the radiation part 201 . The extension part 202 has a feeding point F1 and a grounding point G1. The antenna part ...

Abstract

The invention relates to a flat antenna and a handheld device. The handheld device comprises a flat antennal and a system ground plane; the flat antenna is provided with a first feed point, a first ground point, a second feed point and a second ground point; the first ground point and the second ground point are positioned between the first feed point and the second feed point; and the system ground plane is electrically connected to the first feed point, the first ground point, the second feed point and the second ground point. So the receiving and dispatching quality of wireless signals can be improved.

Description

technical field [0001] The present invention relates to a planar antenna, and in particular to a planar antenna for a handheld device. Background technique [0002] Multi-input Multi-output (MIMO) is a method used to describe how wireless communication signals communicate with each other between multiple antennas. Simply put, MIMO refers to the use of multiple transmitting antennas and receiving antennas at the transmitting end and receiving end respectively, and signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving the service quality of each user. For traditional single-antenna systems, MIMO technology can improve spectrum utilization and enable the system to transmit data at a higher rate in a limited wireless bandwidth. [0003] figure 1 is a schematic diagram of a conventional handheld device using MIMO. figure 2 yes figure 1 Schematic diagram of the signal quality of a planar antenna. Please me...
