dc.description.abstract | 這篇論文提出一個新的平面透鏡天線的設計方法,可以使得透鏡天線具有高的聚焦特性。這樣的透鏡是由許多的同心加圓環所組成,每一個同心圓環的界電係數的分佈都是線性。 這樣的結構使得電磁波射線穿透過透鏡天線後的相位都是相等的。最後用一個設計的例子來說明這種方法的效果,可以得到大約百分之八十的鏡徑效率。 | zh_TW |
dc.description.abstract | A new method of design for a high quality planar dielectric lens antenna is presented. The lens s divided into subzones, each zone with linear - varying permittivity. The construction is such that the phase at the output plane of the lens is equalized for all rays through the zone boundaries. A design example is given to show the effectiveness of the method, which yields an aperture effictiency of 81%. | en_US |
