Background/Objectives: Employing an antenna with the structure of heptagon patch and proper slots to reduce the size of the antenna while keeping the UWB bandwidth. Methods/Statistical Analysis: All the simulations have been done using HFSS software. The geometries of the antenna were determined by implementing parametric studies using this software. In the designed antenna, uniform ground plane prevents back lobs in radiation pattern and makes it suitable for some applications such as medical usages. Findings: Through this design, an antenna that is applied for UWB application can be achieved with a low cost and can be fabricated on a simple substrate. Not only does it cover a favorable bandwidth, but also has a new shape for its patch. The antenna’s small size, desired bandwidth with acceptable gain in comparison to previously designed or fabricated antennas can make it a good candidate for future analyses. Another benefit of this designed antenna is employing probe feeding technique to improve bandwidth as well as other related parameters of UWB antennas. Application/Improvements: All the simulations have been done using HFSS (high frequency structural simulator) software.
