Abstract

The fractal expanded antenna with the configuration of a triangular microstrip patch antenna is presented and analyzed. In the fundamental and higher mode of TFA(Triangular Fractal Antenna), resonant frequencies are controlled by changing the scaling factor. It is observed that increasing scaling factor makes the resonant frequency be spread, and decreasing scaling factor makes it be concentrated. The scaling factor is varied as the expansion and concentration of resonant frequencies. The resonant frequency in each fractal patch element is observed log -periodically. The TFA can be applied to the multiband system.

삼각형 마이크로스트립 패치를 기본으로 프랙털 확장시킨 삼각형 프랙털 안테나(Triangular Fractal Antenna)를 제안한다. TFA의 기본모드와 고차모드에 대한 공진주파수를 스케일링 인자 (scaling factor)를 변화시켜 조절한다. 스케일링 인자의 변화에 따라 공진주파수가 확산 혹은 집중되는 현상을 보인다. 각 프랙털 패치(fractal patch)에서 공진되는 주파수들은 대수 주기적으로 나타난다 이 논문에서 제안된 삼각형 프랙털 안테나는 다중대역 특성을 갖는 시스템에 적용 가능하다.
