Abstract

A compact hyper-band printed antenna design is designed numerically and measurements of a fabricated prototype confirm the predicted 10:1 input impedance bandwidth and radiation characteristics. It is based on an elliptical-slot antenna augmented with a parasitic oval patch and driven with a specially engineered microstrip-line-fed elliptical tuning fork element. The total size of the final optimized antenna is 30 × 40 mm²; it exhibits a -10-dB impedance bandwidth from 2.26 to 22.18 GHz. While the hyper-band performance could be used for high fidelity pulse applications, the antenna also covers the entire ultra-wideband (UWB) spectral range from 3.1-10.6 GHz.
