Performance enhancement of dual‐polarised dipole antenna …
WebNov 23, 2024 · In this paper, a reconfigurable antenna design is proposed to realize independent pattern, beamwidth and polarization reconfiguration at an operating frequency of 2.45 GHz. This antenna is comprised of a dual coaxial-feed driven element surrounded by four varactor loaded size-tunable parasitic elements. WebThe term antenna array most commonly means a driven array consisting of multiple identical driven elements all connected to the receiver or transmitter. A parasitic array consists of a single driven element connected to the feedline, and other elements which are not, called parasitic elements. It is usually another name for a Yagi–Uda antenna . lightning network crypto
