A CPW-Fed Dual-Band Slot Antenna with Circular Polarization
In this paper, a coplanar waveguide (CPW)-fed dual-band slot antenna with circular polarization (CP) is presented. In order to achieve CP characteristic, an asymmetric slot and F-shaped end patch are introduced to a conventional rectangular slot antenna. Moreover, by cutting a T-shaped notch on the ground plane, the axial ratio (AR) bandwidth (ARBW) can be extended. The antenna shows left-hand ...
متن کاملPrinted 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 ...
متن کاملIrregular Circular Fractal Slot Antenna for Dual Wideband Applications
A compact CPW-fed fractal circle monopole antenna with dual wideband is presented for simultaneously satisfying wireless local area network (WLAN) for 2.4/5.2/5.8 GHz application. The antenna consists of irregular shape circles based on the Descartes circle theorem. The simulated -10 dB bandwidth for return loss is from 2.04 to 3.35 GHz and 4.96 to 5.9 GHz, covering all the 2.4/5.2/5.8 GHz WLAN...
متن کاملAn Electrical Model to U-Slot Patch Antenna with Circular Polarization
The microstrip antenna is one of the best antenna structures, due to its low cost and compact design. In this paper, a coaxial feed circularly polarized square patch antenna is designed using the U-slot. The proposed antenna is suited for the RFID readers in the SHF band. This structure of antenna of FR4 substrate (dielectric constant = 3.5), is capable to cover the range of frequency of 2.4 to...
متن کاملTheoretical Analysis of Polarization Rotation angle in Dual Reflector Antenna
Because of special structure, a dual reflector antenna has beam rotation capability in azimuth and elevation directions. In this structure, the antenna beam can be placed in any point in the space by mechanical movement of twist reflector which it is the most important ability of the antenna. Due to the antenna structure, if the polarization of incident wave is linear, it is expected that the p...
