AI Technical Summary

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 internal antenna is relatively close to the user's head when the phone is in use
[0010] Although this antenna construction allows for reduced radiation exposure, further improvements in antenna construction, especially the internal antenna, now also require a reduction in overall device size, while still providing relatively low SAR values

Abstract

A mobile wireless communications device includes a housing and main circuit board carried by the housing and having circuitry thereon. A keyboard circuit board is carried by the lower portion of the housing and has a keyboard section and keyboard circuitry thereon connected to circuitry on the main circuit board. An antenna section on the keyboard circuit board is configured as an antenna and positioned at the lower portion of the housing and has a pattern of conductive traces forming an antenna circuit and connected to the circuitry on the main circuit board. 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...
