An Archimedean spiral antenna is the most potential candidate in the above mentioned applications as the antenna meets most of the above requirements. However. the practical implementation of spiral antenna is challenged by its bidirectional patterns. relatively low …
The band theory is used to explain the theoretical principles of the operation of the spiral antenna. In this paper. a two arm Archimedean spiral antenna is designed using Computer Simulation Technology. (CST). The properties of the active region of the spiral antenna are analyzed in different types of dielectric substrates.
The Archimedean two-wire spiral antenna Abstract: A pair of equally excited but oppositely sensed Archimedean two-wire spirals situated close to one another in the same plane-a doublet-is used to generate a linearly polarized field in which the direction of polarization and phase are controlled or varied independently of each other by rotation of the spiral radiators.
In this thesis. theoretical and practical evaluation of usual spiral antenna is revised. Working principles of both types of planar spiral antennas as Equiangular and Archimedean are introduced. A predesigned microstrip tapered balun used for feeding section of a spiral antenna is …
Abstract. The potential applications such as satellite communication systems. critical military communications. radar warning systems and direction finding systems demand for high
The proposed antenna is composed of an Archimedean spiral antenna (ASA) with an annular ring and additional dielectric substrates with a circular hole. The spiral and ring radiators are printed between two substrates made of FR‐4. with a dielectric constant of 4. 5 …
Archimedean spiral antenna thesis proposal I’ve be a couple of communications within my annual appearance inside the Natchitoches/NSU Folklife Festival and whether I’ll have new books there i thought I’d perform short publish.
