Design of a wideband and dual-polarized CPW-fed monopole antenna for future 5G communications
Résumé
As fast development in communication field, sub-6
GHz spectrum band becomes ultra crowd. Even though Carrier
Aggregation (CA) and higher order modulation used, available
spectrum is still the bottleneck of communication speed and
network latency. Nowadays, more and more companies and
institutes are paying more attention to over 6GHz communication
system research. Recently released news indicate frequency points
are mainly on 12GHz, 15GHz, 28GHz, 38GHz even 70GHz, and
accompanied working bandwidth is about 400MHz to 1GHz.
As working band goes higher, antenna conceptions will also be
updated. A CPW-Fed monopole antenna working in KU-band
with more than 20% relative bandwidth is hereby introduced,
which might be a good candidate for future 5G cellular networks
and also satellite based DBS reception system. Proposed antenna
has small profile lower than g=4 with dual-polarization, which
is thus suitable for base station and mobile device conceptions.
