Abstract
A system includes a wireless radio board, an antenna, and a ground pattern having a radio board ground and an antenna ground. At least a portion of the radio board ground and at least a portion of the antenna ground overlap. The radio board ground could include a first portion in a first layer of the ground pattern and a second portion in a second layer of the ground pattern, and the antenna ground could include a first portion in the first layer of the ground pattern. The antenna ground could further include a second portion in the second layer of the ground pattern. The radio board and antenna grounds could be separated by a minimum distance, such as 0.5 mm or 3.0 mm.
