摘要：

We have developed a compact, mass-producible probe inserted into two holes 1/4 wavelength apart in the narrow side of the reduced height waveguide. The probe consists of two current loops and a directional coupler mounted directly on a single microstrip circuit board thereby greatly reducing the physical size of the probe. Calibrations have shown directivity greater than 20 dB at 4.6 GHz for each of the over 100 probes built.
