Digital pattern synthesis with a compact MIMO antenna of half-wavelength diameter
(2021)The paper presents a compact multiport antenna, with beamforming capabilities and a realized gain of 4.31 dBi with the size of λ/2. The antenna allows digital beamforming with independent control over three parameters: ... -
On the Efficiency of Miniaturized 360° Beam-Scanning Antenna
(IEEE, 2019)The efficiency and beam-scanning performance of a compact, beam reconfigurable antenna are presented. The proposed design provides a 360° reconfigurable bidirectional radiation pattern in the horizontal plane by using phase ... -
Temperature-Responsive 4D Liquid Crystal Microactuators Fabricated by Direct Laser Writing by Two-Photon Polymerization
(2021)Over the past decade, progress in direct laser writing by two-photon polymerization (DLW-TPP) of stimuli-responsive materials has made considerable inroads into the realization of microactuators. With the focus on performing ... -
Out-of-pocket costs near end of life in low- and middle-income countries: A systematic review
(2022)Background Globally, there is a rise in chronic disease, including cancer, major organ failure and dementias. Patients and their families in low- and middle-income countries (LMICs) pay a high proportion of medical costs ... -
