A Broadband Suspended Microstrip Antenna for Circular Polarization
In this paper we propose a circularly polarized (CP) microstrip antenna on a suspended substrate with a coplanar capacitive feed and a slot within the rectangular patch. The antenna has an axial ratio bandwidth (< 3 dB) of 7.1%. The proposed antenna exhibits a much higher impedance bandwidth of about 49% (S11 < −10 dB) and also yields return loss better than −15 dB in the useful range of circul...
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...
متن کاملSuspended Hexagonal Microstrip Antennas for Circular Polarization
Suspended hexagonal microstrip antenna with a single coaxial feed has been proposed for circular polarization. The configuration has been realized by inserting perturbations along two opposite sides of the suspended hexagonal microstrip antenna. The broad bandwidth of 70 MHz has been obtained corresponding to VSWR < 2 and 3 dB axial ratio bandwidth of 16.2 MHz has been achieved for the suspende...
متن کاملA 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 کاملRotation of Linear Polarization Plane and Circular Polarization from Cosmological Pseudo-Scalar Fields
We show that a time evolving pseudo-scalar field coupled to the electromagnetic tensor generates circular polarization and does not only rotate the plane of linear polarization. We compute analytically and numerically the propagation of the Stokes parameters from the last scattering surface for an oscillating and a monotonic decreasing pseudo-scalar field acting as dark matter. PACS numbers: CM...
