A novel Ψ-Shape microstrip antenna and U-slot microstrip antenna using additional slots both providing wide-bandwidths

In this paper, the investigation results of a novel Ψ-shape microstrip patch antenna and U-slot rectangular microstrip antennas (RMSA) by loading the patch with additional slots are presented which provide wide-band performance. A thin microwave substrate has been selected for the microstrip antenna fabrication supported by a foam substrate on top of the ground plane so that the co-axial probe soldering can be easily done on microstrip patch antenna, which makes it suitable for the practical wireless communication applications. Impedance bandwidths of 60% and 46% are achieved for the Ψ-shape and U-slotted microstrip antenna designs.
