Abstract: In this paper, a wide-band miniaturized Conformal conical Archimedean spiral (CCARS) antenna is proposed for Ultra wideband (UWB) communications. The CCARS antenna utilizes the vertical ...

This project provides a mathematical solution for analyzing the motion on an Archimedean spiral, focusing on position calculation, velocity analysis, and trajectory optimization.
