A microstrip antenna incorporating a V-shape slot on its patch is introduced and studied for its impedance bandwidth and radiation characteristics. It is shown that the antenna is inherently broadband, and by optimising the V-parameters its performance can be improved considerably over that of a U-slotted patch. Its stacked configuration is also investigated, using both a conducting patch and another V-slotted patch. Bandwidths as high as 54% are achieved with stable pattern characteristics, such as gain and cross polarisation, within its bandwidth. A detailed investigation is conducted and the effect of all its parameters, such as the substrate dielectric constant and thickness as well as the V-slot length, position, width and angle, are determined and discussed. An experimental study confirms the simulation studies.
