We describe the design of coaxial microwave radiators suitable for localized hyperthermia of neoplasia in the esophagus, brain, and other organs which are accessible through body orifices. These radiators can be implanted surgically and are small enough to be passed through such devices as nasogastric tubes and bronchoscopes. The radiators consist of combinations of cross‐switched half‐wavelength coaxial sections and/or needle antenna terminations. The performance of these radiators, as determined by thermogram recordings in tissue phantoms and the results of in vivo animal tests, is described.
