Broadband L-Probe Fed Patch Antenna Combined With Passive Loop Elements

Abstract

A new broadband L-probe fed rectangular patch antenna electromagnetically coupled to parasitic loop elements is presented. The proposed antenna is analyzed numerically using the moment-method-based electromagnetic simulation (IE3D) and high-frequency structure simulation (HFSS) softwares. The calculated results are in a good agreement with measured data. The impedance bandwidth of a prototype manufactured using a dielectric substrate with the relative permittivity epsi <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</sub> = 2.55 is about 15%
