本論文提出應用於粉粒體流量偵測指向性天線,分別為24 GHz 1×4微帶陣列天線、圓錐號角天線和槽紋號角天線,24GHz 1×4陣列天線饋入網路採等分功率設計,其量測最大增益為8.9 dBi,板材採用Rogers RO4003C玻璃纖維介質板,擁有低的介電常數3.55和極低的介質損耗0.0027,非常適合應用於毫米波頻段,為了讓量測距離提升,設計了圓錐號角和槽紋號角天線,製作材料為鋁,兩款號角天線皆使用24 GHz微帶陣列天線饋入,可以將24 GHz微帶陣列天線的輻射波束更加集中使增益提高,圓錐號角天線經由理論計算和模擬,增益設計為20 dBi,槽紋號角天線結構尺寸與圓錐號角天線一樣,但在光滑內壁上加工了 的槽紋,用微帶陣列天線饋入實際量測的增益為17.6 dBi,與單獨24 GHz陣列天線的增益相比提升了8.7 dBi。
This thesis proposes directive antennas for powder materials flow measurement which are 24 GHz 1×4 microstrip patch array antenna, conical horn antenna and corrugated horn antenna. The 24 GHz 1×4 array antenna feed network adopts equal power design, and its maximum measured gain is 8.9 dBi, the substrate uses Rogers RO4003C, has a low dielectric constant of 3.55 and extremely low dielectric loss of 0.0027. It is very suitable for use in the millimeter wave band.In order to improve the measurement distance, conical horn and corrugated horn antennas are designed and made of aluminum. Both horn antennas are fed using a 24 GHz microstrip array antenna. The radiation beam of the 24 GHz microstrip array antenna can be more concentrated to increase the gain. Theoretical calculations and simulations show that the gain is designed to be 20 dBi. The corrugated horn antenna has the same structural dimensions as the conical horn antenna, but the grooves machined on the smooth inner wall are combined with the microstrip array antenna to measure the overall antenna gain of 17.6 dBi. Compared with the gain of a 24 GHz array antenna, it is improved by 8.7 dBi.
