Abstract
A novel dual and wideband aperture-stacked patch antenna is presented. It consists of a single microstrip patch, which is notched on the radiating patch to obtain dual-band operation and two dielectric substrates and a foam material. By the proper choice of the aperture size and height of a foam material, dual and wideband characteristics could be realised. The measured impedance bandwidth (1:2 VSWR) of the designed antenna at the lower band (860 MHz) reaches 124 MHz and that at the upper band (1960 MHz) is about 663 MHz. Good broadside radiation with high gain (6.92-7.92 dBi) characteristics have also been observed.
