E-H matching device and apparatus and method for automatically matching microwave impedance
 An E-H matching apparatus includes an E-plane branch waveguide connected to an E-plane of a waveguide body, an H-plane branch waveguide connected to an H-plane of the waveguide body, and plungers provided in the E-plane branch waveguide and the H-plane branch waveguide, respectively. The plungers are moved to establish impedance matching between the waveguide and a load. The H-plane branch waveguide has a bend portion formed in close proximity to the waveguide body.
