the PCB and the antenna layers can
be made without electrical contact.
The pin structure also acts as a shield
for the active components, protecting
them from interference and prevent-ing propagation within the substrate
of the PCB. Removing the need for
shielding walls and via holes frees up
valuable circuit board space, which
becomes available for the placement
of active circuits and routing lines. The
die-cast antenna layers also provide
effective cooling for the active circuits
from two sides. This is useful when integrating high-power amplifiers and
CMOS based control circuits onto the
same circuit board, which often require
cooling from different sides.
There are many exciting new
technologies such as 3D printing,
metamaterials and fractal antennas,
that promise to revolutionize antenna technology in the next few years.
They will solve many challenges
that traditional antenna technology
has not been able to overcome and
enable new antenna shapes and applications that are not even possible
with traditional antenna technology.
The unique new approaches will address many of the challenges faced
today in 5G, IoT, SATCOM and radar applications.n
