Design of UWB Small Loop Antenna with Continuous Tuning Frequency 1–10 MHz

Abstract

This paper presents a novel UWB small loop antenna with continuous tuning frequency 1–10 MHz. A prototype of the design is fabricated and measured to demonstrate the effectiveness of the concept. Accurate frequency tuning is achieved by incorporating tolerances of the electronics, utilizing accurate circuit model, and extrapolating capacitor values through high order polynomial curve fitting.
