N2 - This paper presents the comprehensive analytical design and numerical
performance evaluation of novel millimetre-wave (mm-wave) switched-beam
networks, based on the Rotman lens (RL) array feeding concept. These
passive array devices have been designed for operation in the 28-GHz
frequency band, covering the whole 18-38 GHz frequency range. The
primary objective of the work is to conduct a thorough feasibility study
of designing wideband mm-wave beamformers based on liquid-crystal
polymer (LCP) substrates, to be potentially employed as low-cost and
high-performance subsystems for the advanced transceiver units and
large-scale antennas. The presented RLs exhibit significant output
behaviours for electronic beam steering, in terms of the scattering (S)
parameters, phase characteristics, and surface current distributions, as
the feeding systems' primary functionality indicators.
