Current Research

My research at KTH focuses on the design and fabrication of millimeter wave (mmW) waveguide antennas and passive components (from 110 GHz up to 500 GHz) for high data rate communications, radar, and space applications.

The implementation of passive waveguide components at these high frequencies is still a big challenge due to the small feature sizes and the tight tolerances required for achieving high performance devices.

In my research, I use silicon micromachining as the main manufacturing technology to overcome these difficulties. This allows me to fabricate complex RF components at high frequencies like the turnstile OMT shown in the image below. 

This OMT was designed for the 220-330 GHz band for radio astronomy applications and it was published in 2019 in the IEEE Transactions on Terahertz Science and Technology.

My most recent research also involves low-profile waveguide antennas for high data-rate backhaul systems and beam forming networks for multibeam applications.

 

Short CV

I was born in Artariain, Spain, in 1990. I received my B.Sc. and M.Sc. degrees from the Public University of Navarra (UPNA), Pamplona, Spain, in 2014.

From 2013-2017, I was with the Antennas and Microwave Components group, UPNA, where I worked on microwave passive devices and silicon micromachining for RF/THz components.

I joined the department of Micro and Nanosystems in 2017, where my current research focuses in the area of Microwave and THz passive waveguide components.
