Abstract
A novel wideband multilayered microstrip antennas with shorting pins and arc-shaped apertures loaded is designed and fabricated. The antenna consists of two dielectric substrates and a quasi H-shaped circular patch with five shorting pins and four arc-shaped apertures loaded on the upper layer. Multiple layers are employed to achieve wide bandwidth by stacked electromagnetic coupling. The arc-shaped apertures and shorting pins are used to excite multiple modes, which can change the cavity's electromagnetism characteristic with influencing the series-parallel connection inductance, so that the wide bandwidth is obtained. Effects of the key parameters on the wideband performance are also studied, and a set of optimum values is chosen for the antenna design. The impedance bandwidth (VSWR < 2.0) of the proposed antenna reaches 2.59 GHz with the measured results, which means the relative impedance bandwidth is expanded up to 34.7% across 6.17 to 8.76 GHz. Simulation results agree well with measured ones.
