Abstract:
A built-in antenna device for an electronic device for communication used in a multi-band is provided. The built-in antenna device includes a PCB, a first antenna radiator disposed on the PCB, and a second antenna radiator which has the same power feeding point as the first antenna radiator and is disposed at a housing of the electronic device, wherein the first antenna radiator and the second antenna radiator are configured to operate at different frequency bands.
Abstract:
Disclosed are apparatus and method for matching an antenna in a wireless terminal, which are tailored for easy control of impedance matching. A controller is configured to generate state information corresponding to states of the wireless terminal, and providing the state information to a Field Programmable Gate Array (FPGA) unit. The FPGA unit outputs an optimal Tunable Matching Network (TMN) adjustment value corresponding to the state information of the wireless terminal State information may include operating bands/protocols and modes discerning particular environmental conditions impacting electric fields, such as a hand-held condition.
