Problems solved by technology

[0003] However, the FMN scheme requires considerable time in the wireless terminal development process to achieve optimal LC circuit component values ​​to match the antenna
In addition, because the LC circuit device values ​​cannot be changed in response to the electric field state, radio frequency (RF) performance problems frequently occur when the state changes under changing user environments

Embodiment Construction

[0011] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. Like reference numerals are used to refer to like elements throughout the drawings.

[0012] The terms and words used in the following description and claims are not limited to the bibliographical meanings; they are used herein only to enable a clear and consistent understanding of the present invention.

[0013] It should be understood that the use of "a" and "an" in the singular is intended to include plural reference unless the context clearly dictates otherwise. Thus, for example, reference to "one" embodiment and "a" specific embodiment each includes reference to one or more embodiments, elements or features.

[0014] Embodiments of the present invention avoid the disadvantages of the FMN scheme described above by implementing an efficient tunable matching network (TMN) scheme. The TMN scheme uses a variable LC circuit instead of a fixed LC circuit ...

Abstract

Disclosed are apparatus and a 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.

Description

technical field [0001] The present disclosure generally relates to a wireless communication terminal, and more particularly, to an antenna matching apparatus and method for easily controlling antenna matching in a wireless terminal. Background technique [0002] Designing the antenna and its matching circuit within the wireless terminal is critical to achieve the desired wireless terminal performance over the operating frequency range, protocol and environmental conditions. Each transceiver device used for wireless communication includes an antenna, and if a mismatch between the antenna and a transmission circuit occurs, the performance of the transceiver device is degraded. In order to solve this antenna mismatch, conventional wireless terminals employ a fixed matching network (FMN) scheme using a fixed LC circuit (L denotes an inductor, and C denotes a capacitor). [0003] However, the FMN scheme requires considerable time in the wireless terminal development process to a...
