Additive Manufacturing for Broadband Sensors

D-dot sensors, widely used for high-frequency broadband electric ﬁeld measurements, can be
expensive to obtain, have long lead times, and are typically limited to 10 GHz. However, free-ﬁeld
laboratory tests often require measurements beyond those limits. This research explores the
application of additive manufacturing technologies to develop custom D-dot sensors for
applications that require sensing exceeding 12 GHz. Although they appear to have a simple
structural design, these sensors require exceptional precision when manufacturing. By leveraging
the design freedom of additive manufacturing, several mechanical designs are being explored,
simulated, manufactured, and evaluated in laboratory settings. This study focuses on investigating
the optimal additive manufacturing techniques while simultaneously attempting to extend the
usable frequency range of the sensor to 12 GHz and higher.
