Abstract

The simple uniplanar quasi-optical mixer uses the effect of orthogonal modes in the folded slot antenna fed by slotline and coplanar waveguide on opposite sides. The input impedance of the antenna is analyzed with the space domain integral equation technique. Experiments at 11 GHz have demonstrated antenna and mixer operation. The antenna shows reasonable radiating properties. By taking advantage of even and odd modes in the antenna, balanced mixing can be achieved with good conversion loss.<>
