ABSTRACT:
A microwave heating applicator usable in preformed holes in mansonry and the like for heating and dehumidifying areas around the holes is formed from a length of coaxial transmission line. Radiating elements are formed in the outer conductor of the coaxial line for providing an asymmetrical radiation pattern. The radiating elements are provided by forming circumferential axial discontinuities in the outer conductor, each discontinunity having a pair of non-parallel cut edges formed in the outer conductor encircling the line, leaving an asymmetrical open area extending axially between the cut edges. One of the cut edges may describe a plane perpendicular to the coaxial line's z axis while the other cut edge describes a plane which is not perpendicular to the coaxial line z axis. The radiating elements may be provided at intervals along the coaxial line. An end radiating element may be formed having only one edge cut in the outer conductor, the element being bounded by the remote end of the coaxial line with the outer conductor removed therebetween. A flattened radiation pattern may be obtained by orienting adjacent radiating elements with their respective radiating asymmetries angularly rotated 180 degrees relative one another. The interval between radiating elements must be at least on the order of one-half wavelength in the antenna medium of the coaxial line. The applicator may be provided with a microwave-transparent outer protective cover.
