Parasitic antenna
WebJun 27, 2024 · The parasitic patches were formed by quartering a circular patch via two orthogonal slots. The antenna was characterized via the ANSYS HFSS to obtain a low profile and a broadband characteristic at a frequency of 1.6 GHz. The antenna was excited by a perfect lump-port with an input impedance of 50 Ω. In a radio antenna, a parasitic element or passive radiator is a conductive element, typically a metal rod, which is not electrically connected to anything else. Multielement antennas such as the Yagi–Uda antenna typically consist of a "driven element" which is connected to the radio receiver or transmitter through a feed line, and parasitic elements, which are not. The purpose of the parasitic …

WebThe antenna arrays as seen above, are used for the improvement of gain and directivity. A parasitic element is an element, which depends on other’s feed. It does not have its own feed. Hence, in this type of arrays we … WebThe parasitic antenna arrangement is shown below. The elements which are not fed directly are known as parasitic elements & they simply draw their power from the emitted radiation by the driven element that is present nearby. As a result, parasitic elements are activated by electromagnetic coupling since the driving element is nearby.

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. This antenna radiates maximally in directions perpendicular to the antenna's axis, giving it a small directive gain of 2.15 dBi. Although half-wave dipoles are used alone as omnidirectional antennas, they are also a building block of many other more complicated directional antennas.
