碩士 === 高苑科技大學 === 電子工程研究所 === 100 === This thesis is a monopole antenna with wideband application, and the Ansoft HFSS 10 simulator is used to simulate. The return loss in every measure frequencies are under 10dB. The operating bands of this antenna are including LTE. Bluetooth. WLAN. And WIMAX those can be applied for wireless network, the bandwidth more than 25% to fit the definition of Ultra Wide band (500MHz above) 。 This thesis is designed on the shape of octagonal antenna, and is made by one-half wavelength. Due to the characteristics of CPW antenna is symmetry we choice the design operation frequency at 4GHz. The obtain operating frequency between 2.16GHz ~ 6.06GHz and bandwidth is 94.9% which match the LET 2.6GHz~2.8GHz),Bluetooth(2.4GHz~2.4835GHz), WLAN(2.4GHz~2.4835GHz.5.15GHz~5.35GHz.5.725GHz~5.85GHz) and WiMAX (3.3GHz~3.8 GHz)。 In order to lower the operating frequencies, we also use the ”E” type slot to meet the request of ultra- wide band。
