Mubarak Sani Ellis, Zhiquin Zhao, Jiangniu Wu, Xiaoxiang Ding, Zaiping Nie, Qing-Huo Liu, “ A Novel Simple and Compact Microstrip-Fed Circularly Polarized Wide Slot Antenna with Wide Axial Ratio Bandwidth for C-Band Applications,” IEEE Transcations on Antennas and Propag., vol. 64, pp. 1552-1555,2016. Television antenna - Wikipedia The boundaries of each band vary somewhat in different countries. Some older television stations broadcast in horizontal polarization which requires that the antenna elements be horizontal, but most broadcast in circular polarization, so that linearly polarized antennas can receive the signal equally well in any orientation. POLARIZATION SWITCHING/VARIABLE DIRECTIVITY ANTENNA - US ... A polarization switching/variable directivity antenna according to the present invention includes a ground conductor plate 12 on a surface of a dielectric substrate 11, and has a radiation element 13, a directivity switching element 15, and polarization switching elements 16 provided on the ground conductor plate 12 side of the dielectric substrate 11.

linearly polarized radial line slot antenna (RLSA) with experimental performance is presented. The method is beam squinted design. The prototype development processes included specification definition, selection of the cavity's dielectric material and construction of prototype. The production of prototypes is divided into two stages. The development of radial line slot array antenna for ... development. A more beneficial design is the linearly polarized radial line slot array (RLSA) type antenna. The plus side of this antenna (Davis and Bialkowski 1997a) includes high radiation efficiency, low profile, ease of installation (can easily be mounted on roof wall), feed rear-mounted and not subject to leaf and water build-up Design Method, Analysis and Prototypes of Radial Line Slot ...

A dual circularly polarized (CP) omnidirectional antenna based on slot array in coaxial cylinder structure is presented in this paper. It is constructed by perpendicular slot pairs around and along the axis of the coaxial cylinder to realize the omnidirectional CP property, and two ports are assigned in its two sides as left hand circularly polarized (LHCP) port and right hand circularly ... Multi-Band Circularly Polarized Slot Antenna for GPS ... Multi-Band Circularly Polarized Slot Antenna for GPS, Bluetooth and WiMAX Bands Mohammad Bod* and Hamid R. Hassani Abstract|This paper describes the concept, design, and measurement of a multi-band circularly polarized printed slot antenna with a single microstrip feed line. The antenna design for circular Circular Polarization vs. Linear Polarization: Which is ... Q: Regarding antennas, what is the difference between Circular Polarization and Linear Polarization? A: The choice between circular polarization antennas and linear polarization antennas can make a significant difference in an RFID system. Linear polarization occurs when electromagnetic waves broadcast on a single plane (either vertical or horizontal). Linearly Polarized Proximity Coupled S-Slot Back Fed ...
