Dielectric Constant Measurement Technique On Army Ripstop Nylon Material

Today, the wearable textile antenna has become more demanding in huge applications for wireless communication systems, such as wireless medical, health care, mobile communications, and military application. In designing a patch antenna, substrate layer is the main element where the basic performance of the patch antenna highly contributed by the substance. For military purposes, an attachable antenna on the gear suit made from Ripstop Nylon is highly demanded in promoting smart wireless communication systems. Therefore, in this paper, we present a preliminary measurement technique to measure the dielectric constant of Ripstop Nylon material using open-ended coaxial probe method. To clarify the accuracy of measurement, proven method has been calibrated with standard material (deionized water). From the results, dielectric constant for Ripstop Nylon in between 1.32 to 1.44, and closely agree with existed data presented by previous papers.
