Base Station Antenna


I have been working on microwave antenna and RF system designs, particularly focusing on the innovation of cellular base station antennas and arrays. I have developed a variety of novel techniques for antenna element and array designs that addressed future wireless communication challenges and facilitated satisfaction of various industrial requirements. My theoretical analyses, simulation studies, prototype fabrications, and experimental confirmations have successfully led to 8 antenna elements, 3 dual-band antenna arrays, and 1 multi-beam antenna arrays. All of these antennas can be found on this page.
My PhD dissertation is entitled "Key Technologies for Advanced Cellular Base Station Antennas", and it can be accessed here.
