Abstract : This thesis presents a propagation study and antenna design for the Micro-Remotely Powered Vehicle (MRPV). A propagation loss study was conducted to determine the attenuation of various building walls and to select an optimum frequency band for antenna design. An approximate ray tracing model for loss determination was developed and programmed in MATLAB. The computed losses from the model are presented for comparison with measured results. One possible antenna configuration for the MRPV, a circumferential slot, is analyzed and design parameters varied to obtain optimum antenna gain. A prototype of the slot antenna was developed. The antenna patterns, efficiency, and Voltage Standing Wave Ratio (VSWR) are presented.
