Electrically Controlling the Chassis Via A Notching Approach for Improved Handset Performance

We present in this paper an approach to control the chassis through electrically extending the length of the ground plane. With this, improved antenna performance in the handset is achieved. The electrical lengthening is made through a nothing approach to the ground plane longitudinal edges. The notches are carefully designed such that they do not interact with the antenna deteriorating its characteristics or radiate causing interference …
