CYLINDRICAL DIELECTRIC RESONATOR ARRAY ANTENNA WITH PARABOLIC REFLECTOR

This report highlights the investigation on cylindrical dielectric resonator array antenna, CDRA feed with micro-strip transmission line through aperture coupling with the addition of a parabolic reflector. The application of interest for this design is for WLAN data transmission IEEE 802.11 a band. The CDRA proves to be a viable alternative to the current micro-strip patch antenna as it gives higher gain, wider bandwidth and also low radiation loss. The CDRA antenna with parabolic reflector is design for a point to point WLAN application at a center frequency of 5.52 GHz. The design simulation is done using the Computer Simulation Technology (CST) while the substrate prototype is fabricated using printed circuit board (PCB) with the CDRA glued to the substrate using silicon glue. This report consists of an introduction, problem statement, objectives, literature review and methodology used to conduct the research on the CDRA design and its performance. This report also discuss the result obtain through CST simulation and the actual prototype radiation pattern and the maximum gain obtained.
