Abstract

In this paper, we discussed the trapezoidal antenna model in the microstrip structure for UWB communications in the frequency band of $3.1{\times}10.6GHz$. Through the computer simulations for the difference size of trapezoidal monopole microstrip antenna model, the good impedance matching characteristic of return loss less than -10dB(VSWR<2) in all the band of UWB showed. The optimized antenna of this paper also showed the quasi-isotropic radiation characteristics in the horizontal plane and linear phase characteristic of nondispersive property.

본 논문에서는 마이크로스트립구조에서 $3.1{\times}10.6GHz$대역의 UWB 통신을 위한 사다리꼴 안테나모델에 대해 광대역화를 검토하였다. 두 사다리꼴의 마이크로스트립패치 치수를 서로 다르게 한 모노폴의 사다리꼴안테나 모델에 대해 컴퓨터 시뮬레이션을 통하여 UWB의 대역폭에서 반사손실 -10dB(VSWR<2)이하의 임피던스 정합특성을 보이는 안테나의 동작특성을 나타내 보였다. 또한, 본 논문에서 구한 최적화 안테나는 UWB의 전 대역에서 선형위상과 수평면내에서 대체로 무지향 방사특성을 나타내 보인다.
