fabricated with simulated and measured insertion loss
data validating the high conductivity through mm Wave
frequencies. A 3D printed monopole Wi-Fi antenna
was built and tested, showing good performance and
agreement with simulations.
MITRE also has developed a wideband phased array concept that has a complex metamaterial design.
It is based on a PCB design that was not physically
realizable with traditional manufacturing. The design
resembles an egg-crate construction with contiguous
electrical connection (interdigitiated fingers) that is embedded within the orthogonal board interface, as illustrated in Figure 5.1 Multi-material additive manufacturing is thought to be the only practical way to realize this
design. They successfully printed a sample of the cross
in the middle of the array, and a CT-scan showed the
details of all of the fingers confirming the construction
and working on full scale antenna structures.
METAMATERIAL BASED ANTENNAS
Metamaterials are made by arranging naturally occurring materials in a specific pattern that produces an electromagnetic response that is not found in nature. The
periodic structures created are at scales that are smaller
than the wavelengths of the phenomena they influence
and can create materials with negative indexes that control electromagnetic energy in ways that cannot be done
with natural materials. In traditional active electronically
scanned arrays (AESA), phase shifters embedded in
control circuitry steer the beam direction. Metamaterial-
