ABSTRACT:
A cellular telephone handset utilizes an electrically-steered directional antenna to increase the received signal strength when the handset is in a poor signal environment. As a result, the handset reduces the need for an end user to tilt and twirl their head to try and find the direction of the strongest signal strength.
