1. A communication device comprising:
a housing assembly having first and second housing portions connected at respective proximal sides for relative movement between an open position and a closed position about a lateral axis;
a housing position sensor that detects when housing assembly is in the closed position and the open position;
a first antenna array comprised of first and second antenna elements each having an elongated shape and configured to communicate in one or more radio frequency (RF) communication bands, the first and the second antenna elements supported respectively by the first and the second housing portions, the first antenna element proximate to and substantially aligned in parallel with the second antenna element when the housing assembly is in the closed position and separated from the second antenna element when the housing assembly is in the open position;
a first antenna feed/source network communicatively coupled to the first and the second antenna elements and configured to eliminate array cancellations between the first and the second antenna elements when the housing assembly is in the closed position, the first antenna feed/source network transmitting and receiving via one or a combination of the first antenna element and the second antenna element, the first antenna feed/source network capable of adjusting a phase between the first and second antenna elements, and the first antenna feed/source network eliminates array cancellations while the housing assembly is in the closed position by adjusting a phase difference of the first antenna array between 0 and 180 degrees; and
a controller communicatively coupled to the housing position sensor and to a radio frequency (RF) front end comprising the first antenna feed/source network, wherein the controller:
determines, from housing position signal received from the housing position sensor, whether the housing assembly is in the closed position or in the at least partially open position; and
in response to housing assembly being in the closed position, where the first and second antenna elements are proximate to each other and substantially aligned in parallel, configuring the antenna feed/source network to adjust a phase between the first antenna element and the second antenna element to an 180° “out-of-phase” relationship.
