Compact optoantennas for millimeter-wave wireless applications

Abstract

Nowadays there are a lot of applications that request high bandwidth (due to the data that they transport) and high speed of transmission , for example, 5G technology or Video-based applications. The use of photonic systems to achieve these high performance capabilities has been the strike point study research in the last decades. Generation, processing, control and distribution of millimiter (or microwave) wave signals are the main points of study. The Final Master Project that we will discuss throughout this document is based in the study and analysis of compact optoantennas systems for millimiter-wave applications. An optoantenna is an antenna that is feeding by optical signal, once the optical signal has been converted to electric, we can transmit the electrical signal through the antenna. To perform this conversion it is necessary to use a photodetector before the antenna, and in this particular stage of the process we need to do a collimation of the light into the photodiode to have maximum power transfer. Many ideas of how we can perform the maximum power transfer between the feeding optical source and the photodiode will be discuss in this document, and we will analyse what are the different graphical and design software that can (or not) helps as to design the most precise system to achieve our goals.
