- 論文の詳細を見る
A Radial Line Slot Antenna (RLSA) is a planar antenna for DBS reception [1]. It is a kind of slotted waveguide arrays. The conductor loss is so small that high efficiency is expected irrespective of the aperture diameter. On the other hand, since a RLSA utilizes the traveling waves, the frequency bandwidth is limited by the long line effect [2], particularly for a larger antenna. A new Wide-Band RLSA (WB-RLSA) is proposed which halves the waveguide length and widens the frequency bandwidth [3]. This paper presents the design and experimental results of a model antenna. A gain of 33.7 dBi is measured at the edge of 800 MHz bandwidth and its high potential is demonstrated.
