Abstract:To solve the contradiction between the high gain and wide coverage, the concept of the quasi‐conical beam is proposed by using the high‐gain pencil beam electrically switching along a cone to make full use of time redundancy. In a periphery‐fed Fabry‐Perot (FP)‐type multi‐beam antenna, the electrically switching is used to activate the different port corresponding to the different beam for the beam switching in the azimuthal plane, and the varying frequency is used for the continuous scanning in the elevation … Show more
