Abstract
An apparatus and method for antenna matching according to a position and an angle of a portable terminal is provided. Operations of the portable terminal include, when at least one of a position and an angle of the portable terminal is changed, determining an optimal Tunable Matching Network (TMN) set value corresponding to the position and the angle, and performing antenna matching according to the optimal TMN set value.
Claims20
A method for operating a portable terminal, the method comprising:
- determining an optimal Tunable Matching Network (TMN) set value corresponding to at least one of a direction and an angle of the portable terminal when at least one of the direction and the angle of the portable terminal is changed;
- and
- performing antenna matching according to the optimal TMN set value,
- wherein the determining of the optimal TMN set value comprisesdetermining the optimal TMN set value in a Look-Up Table (LUT) using the direction and the angle as look-up parameters.
