Abstract: Provided is a method for designing multiband antenna using a genetic algorithm unit linked to an electromagnetic wave analyzing unit and to a computer-readable recording medium for recording a program that implements the method. The multiband antenna designing method can design an antenna having an optimal structure by combining a genetic algorithm, one of global optimization techniques, with a full electromagnetic wave analyzing program Quick Finite Difference Time Domain (QFDTD). The method of the present research includes the steps of: a) at the full electromagnetic wave analyzing unit, analyzing an antenna structure contained in an input file and linking the antenna structure to the genetic algorithm unit; b) at the genetic algorithm unit, generating an initial group that expresses the antenna structure; c) at the genetic algorithm unit, evaluating cost functions by using the antenna structure analysis result; and d) at the genetic algorithm unit, designing an antenna by selecting objects based on the cost functions, mating the selected objects and generating mutants.

Abstract: PROBLEM TO BE SOLVED: To simplify a power transmission and a directivity error detection structure for tracking by using a power transmission and a DC motor which generate small noises and making a tracking speed quicker. SOLUTION: Active modules 120, 130 supply two signals received from array antennas 100, 110 to a power combining portion 140 to combine them. A frequency converter portion 150 supplies a bias from a signal distribution/detection portion 160, and converts a satellite signal into a signal of a frequency band lower than that. The distribution/detection portion 160 distributes the satellite signal received from the converter portion 150, supplies it to a rotary joint 190, receives a tracking signal selection signal from a satellite tracking portion 170 for detecting a tracking signal, and detects the strength of a signal of a desired channel. The control portion 170 carries out satellite tracking algorithm, supplies a control signal for phase transition to the active module 120, and supplies a motor control signal to a power transmission portion 180.

The electronic absorbing unit(16) absorbs an electronic wave reflected from a rotor contact of a circuit board to reduce an influence to a resonation of the antenna(17). Thus, the antenna(17) maintains its inherent characteristics at the internal side likewise at the outer side, thereby faithfully performing its role. The electronic absorbing unit(16) absorbs even an electronic wave directing to a human body after being generated from the front side of the mobile phone(10), as well as the electronic wave generated from the antenna(17). The electronic wave absorbing unit(16) includes two walls(16A,16B) that meet at 90°and form angular L-shape. The first wall(16A) is attached on the circuit board, and the second wall(16B) is protruded from the surface of the circuit board at one side of the first wall(16A) and extended to the inner face of the rear wall of the case(11).

Abstract: PURPOSE: An antenna-built in mobile phone for reducing electronic wave absorption rate is provided to allow a user to stably and reliably carry a mobile phone by mounting an antenna inside the mobile phone and positioning an electronic wave absorbing unit to remove or at least considerably reduce the amount of a harmful electronic wave absorbed to a human body from the mobile phone body and the antenna. CONSTITUTION: An electronic wave absorbing unit(16) is installed between an antenna(17) and an internal circuit(19). The electronic wave absorbing unit(16) absorbs an electronic wave reflected from a conductor plate constituting the circuit board(19), to thereby reduce influence to a resonation of the antenna(17). Thus, the antenna(17) maintains its intrinsic characteristics even inside the mobile phone(10), thereby faithfully playing its role. The electronic wave absorbing unit(16) absorbs even an electronic wave directing to a human body after being generated from a front side of the mobile phone(10). Thus, an amount of electronic wave radiated while the user carries the mobile phone, that is, an SAR(specific absorption rate), can be remarkably reduced.
