Truncated 2-D Gutman Lens Antenna With Planar Feeding Surface for Stable Wide-Angle Beam Scanning in Millimeter-Waveband
IEEE Transactions on Antennas and Propagation（2023）
摘要
A truncated 2-D Gutman lens (GL) antenna (GLA) with planar feeding surface is investigated for millimeter-wave (MMW) applications. To flatten the feeding surface of Luneburg lens (LL) while maintaining the wide-angle scanning capability, three effective measures have been taken. First, the focal points of LL are shifted to the interior to obtain GL (f = aR, 0 更多
