| 總結: | This project presents the design with optimum geometry of an UWB rectangular
patch antenna. To achieve an UWB characteristic, a patch antenna is designed before
proceeding to the bandwidth optimization technique for the proposed antenna. The
configuration of patch antenna has a partial ground and addition of two steps in the
bottom edge of the patch and one slot in the middle of the patch. The antenna was
designed and optimized using CST Microwave Studio (CSTMWS). The proposed
antenna’s parameters were optimized with various options such as differing the
ground plane length, differing the width of feed line, with different slot positions and
different slot widths, and found to operate satisfactorily. An optimized bandwidth has
been noticed in this design. Moreover, the antennas structure offers great advantages
due to its simple designs and small dimensions. The antenna has been fabricated
using FR-4 substrate and tested using the network analyzer which has range between
to 3GHz to 13GHz at the Radio Frequency (RF) Laboratory. The antenna
performance showed agreement between both simulation and measurement results
with only some small deviation and this observed deviation is due to the different
numerical modeling and meshing techniques. |
