Abstract

In order to design small printed antenna restricted within narrow area of $30mm{\times}8mm$ for the Zigbee module and improve its return loss, meander slot antenna with a floating conductor as the parastic element has been proposed. The resonant frequency and bandwidth(VSWR${\leq}$2) of the antenna designed and fabricated in the present study is about 2.44GHz and 113MHz respectively. The radiation pattern is almost similar to that of dipole antenna within the operation frequency range. Also the radiation efficiency and gain of the proposed antenna is more than 60% and 2.7dBi respectively. It has been observed that the characteristics the proposed antenna mentioned above satisfy the specification required of the Zigbee application. In order to validate the proposed antenna, some simulated and measured results are presented and compared.

지그비 모듈용 소형 PCB안테나를 $30mm{\times}8mm$의 좁은 영역으로 제한된 공간에서 구현함과 동시에 안테나의 반사손실을 개선시키기 위하여, 기생소자로 접지면과 이격되는 도체를 가지는 미앤더 슬롯 안테나가 제안된다. 본 논문을 통해 설계되어 제작된 안테나의 공진주파수는 대략 2.44GHz이고, 대역폭은 113MHz(VSWR${\leq}$2)이다. 방사패턴은 동작주파수영역에서 다이폴 안테나의 방사특성과 거의 유사하고, 안테나의 효율 및 이득은 각각 60% 및 2.7dBi이상의 값을 가진다. 이러한 안테나의 모든 특성들은 지그비에 응용되기 위해 요구되어지는 규격을 모두 만족함을 알 수 있다. 본 논문이 제안하는 안테나의 타당성을 보여주기 위해 모의실험 결과 및 측정결과를 비교하여 제시하였다.
