Abstract: Spherical lens generalizely can only be used to multiple beams in one dimension previously.Multilayer feed antennas placed parallelly in another dimension,scanning in two dimensions is realized.The relationship between displacement of feed antenna and scan angle is analyzed based on the coordinate transformation approach and by using a combined GO/PO method.The antenna is composed of a homogenous spherical lens and multiple layer planar feed antennas.The beam scanning in azimuth and elevation can be achieve...
