Another common method is to employ a plane reflector
or a metallic cavity box located the slot antenna.

ABSTRACT: A box-type low cost, environment friendly, solar oven was constructed and tested alongwith the plane reflector mirrors.
A plane reflector to a box type solar cooker was explained by Abdullah and Hussain .
The present research deals with the performance study of sun solar oven using plane reflector mirrors.
We have used plane reflector mirrors commercially available in the market and also suitable to economic point of view .
In , the planar array of IMPATT or Gunn-diodes is placed in a small distance from the total plane reflector
Figure 6 shows the effects on simulated peak gains and SWRs under the conditions of adopting a horned reflector, a box-shaped reflector, or a planar plane reflector
. Among them, the fence heights ([H.sub.G]) of the box-shaped and horned reflectors are the same.
