The Moxon antenna or Moxon Rectangle is a simple and mechanically robust two-element parasitic array antenna. It takes its name from the amateur radio operator Les Moxon (amateur radio call sign G6XN).The design is rectangular, with roughly half the rectangle being the driven element and the other half being the reflector. It is electrically equivalent to a two element Yagi antenna with bent elements and without directors.
Because of the folded ends, the element lengths are approximately 70% of the equivalent dipole length. The two element design gives modest directivity with a null towards the rear of the antenna yielding high realized front to back ratio.
The Moxon antenna is popular with amateur radio enthusiasts for its simplicity of construction.
