Designing a Butler Matrix Beamforming Network with RF Modeling

Caty Fairclough June 27, 2017

When looking for a cost-effective feed network, engineers can turn to the Butler matrix as a potential solution. This passive beamforming feed network is used with phased array antennas, which have applications in upcoming technologies like 5G. To efficiently analyze and design Butler matrix feed networks, we can turn to the COMSOL Multiphysics® software and the add-on RF Module.

The 5G mobile network and Internet of Things (IoT) are two hot topics in the RF and microwave industry. New developments in these wireless applications call for much higher data rates, active electronically scanned arrays (AESA), phased array antennas, and multiple-input-multiple-output (MIMO) technology. It is important to reduce the time and cost during the process of prototyping and manufacturing these applications. Using simulation and apps, we can streamline the development cycle of wireless communication designs.

Think about the “ideal” wireless network. Data would download at ultrafast rates. We could be connected anywhere in the world and expect quality performance every time we use our devices. An ideal wireless network would be, above all, reliable — no dropped calls, undelivered messages, or waiting for a web page to open. To meet the specific performance requirements of this ideal network, 5G, there are certain RF designs that engineers can consider to transform such technology into a reality.

As you leave for work, your garage door closes and texts your office coffeemaker to start brewing a fresh pot. During the day, your sprinkler system gets a weather report that it’s going to rain and cancels its afternoon watering. This isn’t a futuristic television show, it’s the Internet of Things, and with the next generation of wireless communication, 5G, it’s coming soon. First, we need to optimize the performance of existing mobile device antennas.
