A Circularly Symmetric Antenna Design With High Polarization Purity and Low Spillover

Printed wideband CPW-fed slot antenna with high polarization purity

This paper introduces a novel compact wideband CPWfed slot antenna comprising of an E-shaped patch that is excited with a trident shaped feed-line structure. The antenna design exhibits a very wide operating bandwidth of over 168% with S11 < −10 dB in the frequency range 1.6 to 18.9GHz. The antenna’s radiation characteristics are stable across this wide bandwidth. The proposed antenna exhibits ...

Circularly Polarized Proximity-Fed Microstrip Antenna with Switchable Polarization Ability

Design of Dual-feed Dual-polarized Micro- Strip Antenna with High Isolation and Low Cross Polarization

Abstract—A broadband dual-feed dual-polarized microstrip antenna with low cross polarization and high isolation is presented. The dualorthogonal linearly polarized mode is excited by two different feed mechanisms from a single circular radiating patch. One of the two modes is excited by a pair of L-shaped probes with a 180◦ phase differences, and the other is excited by an H-shaped aperture. Th...

High Gain Antipodal Fermi Antenna with Low Cross Polarization

Antipodal Fermi antenna (APFA) that uses an antipodal feeding section is proposed and its fundamental characteristics are presented. It is shown that the cross polarization level is decreased by 5–10 dB by the presence of the corrugation. It is also found that high gain, low VSWR and low side lobes and low back lobes are obtained. The mechanism of operation principles is discussed by using FDTD...

Designing a Multiband Multi Polarization BTS Antenna

In this paper, a new antenna is presented which has an application in cellular telecommunication systems. The designed antenna works at the frequency range of 1900-2600 MHz which is able to cover 2G, 3G and 4G (LTE) services of the cellular telecommunication. In this paper, the micro-strip structure has been used to design the antenna. The shape of the patches is triangular where a peripheral r...
