A SLOTTED WAVEGUIDE APPLICATOR FOR CONTINUOUS FLOW GRAIN DRYING

摘要

A slotted waveguide antenna was designed and developed with series slots cut on the broad side that constituted a popular means of coupling microwaves with grain for drying. The radiating characteristics of the slotted wave guide antenna Mounted in a setup that simulated the coupling to a grain Conveying tube were studied at a frequency of 2.45 GHz. The Antenna consisted of a WR-340 wave guide made of copper. The effect of the slot inclination angle ￠, moisture content And the shape of the slots were investigated.
