Abstract
A slot antenna includes an antenna guide formed with a recess, a dielectric member received in the recess, a slot plate held in contact with the dielectric member; and a waveguide connected to the antenna guide for introduction of microwaves. The slot plate is uniformly supported by the dielectric member. Alternatively, the slot plate is provided with an expansion absorbing region, so that the slot plate is displaceable relative to the dielectric member.
