Loop Antenna Design

Loop Antenna Design

This study focuses on the design, construction, and evaluation of a 50 Ohm loop antenna for the 434 MHz band. Beginning with a full-wave round loop antenna, the design evolves into a 2:1 rectangular loop, with experiments conducted to assess prototype performance and the effects of material choices.
