A planar low-profile meander antenna design for wireless terminal achieving low self-interference

In this paper, a new internal antenna used for wireless terminal is proposed. The current of this antenna is mostly distributed on the antenna radiator itself, rather than on the main board of the wireless device. As a result, the chance of having self-interference issues, which usually result in receiver desensitization in wireless radios, can be significantly reduced. The antenna has better radiation performance in the vertical polarization with a low profile, and the average gain of this antenna is good as well. Both simulation and measurement results demonstrate the proposed design.
