Abstract :
In this paper, the cavity slot antenna with the H-shape slot was proposed for the implanted antenna. Numerical results show that the proposed antenna resonates well at 2.45 GHz. In order to simplify the measurement, the antenna is fabricated using the scale model which is 2.5 times larger than original dimension of the antenna. The antenna characteristics are measured in the developed 2/3 muscle-equivalent phantom. The results show that the fabricated antenna works at 980 MHz band as expected. The antenna characteristics for the calculation and the measurement corresponded. From these results, it is confirmed that the proposed antenna can be used as the implanted antenna.
