Introduction: 2 4GHz Waveguide With Circular Polarization

By

In this video I show you how to build a circular polarised waveguide for 2.4GHz. I decided to use a cloverleaf antenna as the driven element with a toilet brush holder as the waveguide. It must be noted that the waveguide in this version is not physically connected to the driven element as doing so will affect the VSWR. As I show in testing this is a powerful waveguide when used with a matched antenna with circular polarization and although powerful it is extremely directional with a beam width of 30 degrees.
