中文摘要 | 本文中設計一個寬頻雙頻帶橢圓形狀槽孔微帶天線,架構簡單,使用天線模擬軟體IE3D做天線設計與模擬。在FR4印刷電路板上製作橢圓形狀槽孔及耦合微帶饋送線,經由實作與量測後,其共振頻率分別是2.4GHz及5GHz兩個頻帶。在2.4GHz頻帶時的阻抗頻寬S[8e56]≦-10dB可達20.1%,天線最大增益是6.5dBi。在5GHz頻帶時的阻抗頻寬S[8e56]≦-10dB可達120.4%,其中在5.25GHz及5.75GHz兩頻帶時,其天線最大增益分別是7.2dBi及6.5dBi,可以滿足無線區域網路室內外使用。 |
英文摘要 | A broadband elliptical slot microstrip antenna is designed. Its structure is simple. This antenna is analyzed and optimized by using the IE3D software. The elliptical slot and microstrip coupled feed-line are built on the FR4 printed board. The prototype are fabricated and measured. The dual-resonant frequency bands are 2.4GHz and 5GHz. At 2.4GHz, input impedance bandwidth is 20.1% for the S[8e56] ≦ -10dB, with the peak gain of 5.5dBi. At 5GHz, input impedance bandwidth is 120.4% for the S[8e56] ≦ -10dB, with the peak gain of 12.1dBi for 5.25GHz and 10.5dBi for 5.75GHz. It is suitable for WLAN applications. |
