LEAKY-WAVE ANTENNAS FOR MEDICAL APPLICATIONS Abstract A device (400) for directing energy to a target volume of tissue includes 5 an inner conductor (420) having a length and an outer conductor (460) coaxially surrounding the inner conductor (420) along the length. The outer conductor (460) has a proximal portion and a distal portion. The distal portion of the outer conductor (460) is provided with a number of apertures N (401, 402, 403, 404) defined therein for radiating energy, where N is an integer 10 greater than 1, each aperture (401, 402, 403, 404) having a size and extending at an angle relative to a longitudinal axis of the outer conductor (460). At least one of the size and the angle of each aperture (401, 402, 403, 404) is varied in relation to the other apertures N-1 (401, 402, 403, 404) such that the energy radiated along the distal portion is substantially uniform. 15 Fig. 4 941575 (2547704 1) ---900 901 913 903 --- --------- ----------------- ------- - ---- -- ---------- -- ~920 920 912-902- 914-1 904- 960 1011 1013 1015 ,-1000 1001 1003/ 1005/ - --------- -- --------- ------ 1020 1012 1014 l 1060 -1100 1101 1102 1103 11114115 1116 --- --- - -- -- - - ----- ------ ------ 1120 1160 1111 /1112 /1113/-1104/-1105/'1106 |
