Gunn Diode Power Combining in Open Resonator with Microstrip Array
ABSTRACT
Millimeter-wave band Gunn diodes power combiner is experimentally tested. The oscillation system is represented by a semi-spherical open resonator (OR) with a four-element microstrip array (MSA) positioned on a plane mirror. An active element is installed under each of the radiators of the grating. Comparison of the spectral characteristics and amplitude distribution of the fields in the semi-spherical OR and the resonator with MSA is provided. The dependences of the output power versus the distance between the mirrors are investigated for one, two, three and four diodes. Promise of application of a multi-element MSA in the OR for creation of the power combiners of the semiconductor elements is demonstrated.
