Abstract: A wireless communication device (200) is provided, the wireless communication device (200) can include at least one antenna (240), the antenna (240) positioned beneath the face plate (252) and base plate (255) of a user interface (245) of the wireless communication device (200) in which the antenna (240) can be configured to communicate with a signal source.

Abstract: A multi-band antenna (10) includes one or more a loop portions (12) substantially defining operation in frequency ranges covering between approximately 800 MegaHertz and approximately 1.0 GigaHertz and between approximately 1.8 GigaHertz and approximately 2.0 GigaHertz, a surface plate portion (14) having a length (15) substantially defining operation in a frequency range between approximately 1.7 GigaHertz and approximately 1.9 GigaHertz, and a slot (16) within the surface plate portion having a length (17) substantially defining operation in a frequency range between 5 and 6 Gigahertz (WLAN). The antenna can further include a resonant stub (18) having a length (19) substantially defining operation in a frequency range of approximately 2.4 Gigahertz. The antenna can be a unitary radiating element having a feed element (9) and a ground port (7). Operationally, the antenna can function in 6 bands and can be independently tunable in a majority of the 6 bands.
