| Summary: | 碩士 === 中華大學 === 電機工程學系碩士班 === 100 === The purpose of this thesis is based on the design and testing of the miniaturized antenna for wireless sensor network communication module. The design goals of the communication distance is required to reach 50 ~ 100m. Taking into account the cost reduction, the miniaturized antennas will be integrated in ZigBee module PCB board.
The contents of this thesis include PIFA (Planar Inverted-F Antenna) antenna design, the balun circuit design and adjustment of the operating frequency in order to comply with the IEEE 802.15.4 the ZigBee standards. Newly designed miniaturized PIFA antenna radiation pattern simulation results are consistent with the measured results. Balun circuit design uses the transmission lines and passive components. Differential impedance as seen from the RF port towards the antenna will be matched to TI CC2530 optimum load impedance. Finally, we will show the system measurement results of the ZigBee modules. In the condition of output power 4.5dBm, when the communication distance is close to 100m, PER are still less than 1%.
