中文摘要 | 本文在探討TM₀₁激勵下,圓導波管上槽列結構所產生的輻射場形。在此著者經由程式設計算出,四元槽列、六元槽列、八元槽列,而開口夾角分別為α=45°、90°、135°,在工作頻率各為F=5 GHZ、7.5 GHZ、10 GHZ,所產生的功率場形。經由比較得知頻率增大時,會使輻射主葉變尖狹而轉近軸向且副葉隨之增多。此現象在槽數越多,開口越大時,則愈為明顯。 |
英文摘要 | In this paper, the radiation patterns produced by slot array on the TM₀₁ excited circular waveguide are investigated. The power patterns for the various structures are presented, including 4-element, 4-element, and 8-element arrays, with slot angle α=45°, 90°, 135° under operating frequency of 5 GHZ, 7.5 GHZ, 10 GHZ respectively. It has been shown that, the higher the frequency is used the narrower the main lobe becomes, the more for its direction tilt toward the axis, and the higher side lobe levels appear. This fact will be more distinctively present for the arrays with the large number of slots and larger slot angle. |
