Description
Summary:The extensive requirements for small Ultra wideband (UWB) communication systems lead to design active and small size antennas. In this research two rectangular microstrip antennas were designed to cover the UWB operating frequency of 7.5 GHz starting from 3.1 GHz up to 10.6 GHz. The simulation and prototype designs are presented in this paper using CST microwave studio software tools and printed circuit board, respectively. The designs satisfy the requirements of UWB technology and according to the geometrical shape, one is called prong-shape patch antenna and the other is rake-shape patch antenna. The simulated results for return loss (S11) and radiation pattern have been demonstrated that the antenna designs are suitable for UWB communication systems. The measured results for same parameters were concluded by network analyzer and anechoic chamber to reinforce the performance of these antennas in wireless UWB applications. After confirming the performance of these designs, the comparison was done between the two to see the advantages in use.
