Future satellite platforms and 5G millimeter wave systems require Electronically Steerable
Antennas (ESAs), which can be enabled by Microwave Liquid Crystal (MLC) technology …

Electromagnetic metamaterials have been developing rapidly and attracted worldwide
attentions since the concept has been proposed due to their powerful ability in controlling …

Cheap and ubiquitous sensor systems will shape the coming decades. There is an
emerging class of small high-performance electronic devices such as mobile phones …

This paper presents a millimeter-wave fully differential transformer-based passive reflection-
type phase shifter (RTPS) capable of performing full span 360° continuous phase shift from …

A tunable frequency selective surface (FSS) with beam steering capability is presented. The
FSS is used as a transmitarray with a bandpass characteristic in Ku-band. The periodic sub …

For the first time, a 2-D electronically steered phased-array antenna with a liquid-crystal (LC)-
based variable delay line is presented. The structure, which is designed at 17.5 GHz …

A novel continuous tunable phase progression beamforming feeding network is proposed
using 4× 4 Butler matrix and tunable phase shifters. To tune the progressive phase …

This letter presents a highly miniaturized continuously tunable microstrip line phase shifter
from 10 to 67 GHz. The design takes the advantage of the microstrip line topology by a …

For the first time, a liquid crystal (LC) filled lens antenna is investigated for beam steering in
this paper. The LC's anisotropy is applied inside a semicircular shaped parallel-plate …

This letter presents a planar endfire Yagi-Uda antenna phased array fed by a corporate
network. The phase of each radiating element is controlled by a loaded line phase shifter …
