碩士 === 明新科技大學 === 電機工程研究所 === 100 === As the vigorous development of wireless communications, the network from wired to wireless era, wireless system of antenna is believed to play a more important role. Wireless systems using the 2~3.8GHz and 5~6GHz frequency band are very popular, such as Bluetooth, Radio Frequency Identification (RFID), Worldwide Interoperability for Microwave Access (WiMAX), Wireless Fidelity (WiFi), Wireless LAN (WLAN). In this these’s, slot structure is mainly used to simulate and design for planar antenna. Changing the metal radiating slot is also used to achieve and control of the resonance frequency and efficiency. This research used IE3D simulation software to design and produce the slot planar antenna. Slot antenna exhibit better impedance matching, good radiation efficiency and large bandwidth. The slot planar antennas were fabricated in this these’s by changing the size of slots radiating metal and using the bending slot to achieve the desired resonant frequency, Using mutual resonance effect of multi-slot broadband antenna is also designed. The fabricated antennas can be used in microwave band. These antenna can be applied in 2.45GHz RFID and 3.5GHz WiMAX dual-band, 3.5GHz WiMAX, 5.5GHz Wi-Fi, 2.45GHz RFID and 5 ~ 6GHz of WiMAX and WiFi dual-band, respectively.
