Ultra-wideband planar monopole antenna with parametric study

摘要

Broadband planar trapezoidal monopole antenna is proposed and an analysis of parametric change is given. Techniques are applied to preliminary structure to obtain better impedance matching and broader bandwidth. The proposed Ultra Wideband planar monopole antenna has an operating bandwidth of 0.55-11.5-GHz (S₁₁⇐⇐10⇐dB) and a gain of 1⇐9.5⇐dB.
