In the research project, a design concept of the mm-wave antenna array operating at 38 GHz is proposed by using a 64-element micorstrip patch antenna array. Theoretical and experimental study validates the design approach for the use of the Fifth generation (5G) wireless communication system.
This paper presents performance enhancement of a conventional circularly-polarized (CP) microstrip patch array using anisotropic metasurfaces. In addition to boresight gain, axial-ratio and impedance bandwidth amplifications, sidelobe levels suppression were also focused.
This paper presents a structure of half-width two-dimensional periodical perforated microstrip on uniform ground. Perfect magnetic conductor (PMC) boundary and perfect electric conductor (PEC) boundary are applied at the edge of the half-width, respectively. The dispersion curves show that different left-handed and right-handed modes are excited with the perforated periodic structure when PEC boundary...
This paper reviews the past and current research progress in microwave antenna applications using 2D planar metamaterials or metasurfaces. Firstly, we revisit the definitions of metamaterial and metasurface, and the applications of the ultra-thin metasurfaces for low-profile printed antennas in microwave frequency regime, for the purposes of size reduction and performance enhancement. Then we summarize...
This study proposes a simple self-calibration system that involves applying the phase-match method (PMM) in the far-field calibration of a deployed active array. An 8-element microstrip antenna array was applied to validate the proposed method experimentally.
