We propose an interstitial coaxial antenna with a choke embedded in the outer conductor and with an arrowhead cap for microwave ablation therapy, operating at 2.45 GHz. The cap consists of ceramic and conductor. The heating is suppressed along both the direction in the tip side and the feeding side of the antenna because of the cap and the choke. In addition, a catheter is not required. We numerically clarify these advantages by analyzing the temperature distribution of a spherical breast tumor.
