Abstract
In the modern world researchers are continuously looking for faster, and more efficient forms of communications. A need for the ability to maximize the channel bandwidth available while maximizing the signal to noise ratio will be critical in the years to come. As the society becomes more dependent on wireless technology, and communications the required data rates to sustain our needs will skyrocket in the coming years. There are a number of emerging solutions to this problem, one of which is to look to higher frequencies where more bandwidth is available due to a lack of use. In order to achieve this solution a system must be built that can both achieve a higher range of frequencies without compromising the wireless fidelity of the signal being transmitted. Over the years an attempt to solve this problem has come in the form of many different types of Beamforming. Analog beamforming is the most basic form of beam steering and has the benefits of a maximized signal to noise ratio (SNR). While Digital beamforming is more flexible in allowing you to deal with different ranges of frequencies it however has an extremely high power usage that is currently expensive to be commercially viable. This leads to the idea of creating way to induce both analog and digital beamforming into a single system. A system which can have to flexibility to work in almost any frequency range offered by digital systems while achieving the same degree of accuracy and power that come with an analog system. A commercially viable system efficiency would be able to satisfy the needs of growing demand by supplying a near limitless bandwidth supply with a high signal fidelity. At the University of Delaware, it is hoped that the Vector Modulator will be able to fulfill the technological demands of a growing world while being more economically friendly compared to competing ideas.
