Problems solved by technology

The internal antenna is protected by the case of the mobile device, so it is more durable than an external antenna, which can be inconvenient and make the mobile device difficult to use, especially in environments with limited space
[0007] However, one potential disadvantage of a typical internal cell phone antenna is that the intern

The keyboard circuit board preferably comprises a flex circuit.

Description

technical field [0001] The present invention relates to the field of communication devices, and more particularly, to mobile wireless communication devices and related methods. Background technique [0002] Cellular communication systems continue to grow in popularity and have become an integral part of personal and business communications. Cellular telephones allow users to place and receive voice calls in most places they travel. Furthermore, as cellular telephone technology has grown, so has the functionality of cellular devices. For example, many cellular devices now include Personal Digital Assistant (PDA) features such as calendars, address books, task lists, and the like. Additionally, such multifunction devices allow users to wirelessly send and receive electronic mail (e-mail) messages and access the Internet over, for example, cellular networks and / or wireless local area networks (WLANs). [0003] Even so, as the functionality of cellular communication devices c...
