Leaky-wave antennas for medical applications

摘要

A device for directing energy to a target volume of tissue includes an inner conductor having a length and an outer conductor coaxially surrounding the inner conductor along the length. The outer conductor has a proximal portion and a distal portion. The distal portion of the outer conductor is provided with a number of apertures N defined therein for radiating energy, where N is an integer greater than 1, each aperture having a size and extending at an angle relative to a longitudinal axis of the outer conductor. At least one of the size and the angle of each aperture is varied in relation to the other apertures N−1 such that the energy radiated along the distal portion is substantially uniform.

1. A device for directing energy to tissue, comprising:
an inner conductor having a length; an outer conductor coaxially surrounding the inner conductor along at least a portion of the length, the outer conductor having a proximal portion and a distal portion, the distal portion of the outer conductor including a plurality of conductor apertures defined therein; and a plurality of inclusion elements disposed substantially adjacent to an edge of a corresponding one of the conductor apertures, each inclusion element extending beyond the edge of a corresponding one of the conductor apertures and inwardly toward the inner conductor at an angle relative to a plane substantially coextensive with the corresponding one of the conductor apertures.
