Effects of shell and body tissue simulating liquid (BTSL) thickness on capsule antenna performance

Abstract

In this paper, the study of shell and body tissue simulating liquid (BTSL) thickness and its effects on capsule antenna performance at 2.45 GHz were presented. Two simulation setups which consists two different sets of shell and BTSL position near the capsule antenna were used in the simulation process. The reflection coefficient, directivity, gain and efficiency performance in those simulation setups were determined and compared. The influence of human tissue thickness on the antenna behavior must be considered.
