Abstract 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 waveguide made of
copper. The effect of the slot inclination angle 0, moisture content and the
shape of the slots were investigated. The results indicated 55° as an optimum
slot angle for slots having (l width of Key Words: Slotted waveguide, antenna,
radiation, moisture content, drying, coupling characteristics |
