A Pattern Synthesis Approach in Four-Dimensional Antenna Arrays with Practical Element ModelsBarrier ribplasma display panel (PDPSU-8 photoresisttransparentThis paper introduces a novel approach for the synthesis of array patterns in four-dimensional (4-D) antenna arrays, taking into account practical ...
This synthesis algorithm designs a linear array for a specified directivity or beamwidth. Antenna Magus arranges the elements of the array along the x-axis. The main lobe of the resulting pattern is a body of rotation about the x-axis, with the peak directivity in the +x direction. ...
