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 کاملSingle-Layer Dual-Band Dual-Linear-Polarization Reflectarray Antenna with Different Beams for Each Band
A novel single-layer unit cell structure is proposed to design a dual-band dual-linearpolarization reflectarray antenna with different beams for X and Ku bands. The unit cell structure is composed of a circular ring and two cross bow-tie structures combined by a circular patch. Five tunable geometric parameters can be optimized to achieve the required phase distributions of the reflectarray ant...
متن کاملLow Profile Dual Spiral-Loop Antenna over Electromagnetic Band-gap Ground Plane for Circular Polarization
Electromagnetic band-gap (EBG) structures exhibit unique electromagnetic properties that have led to a wide range of applications in antenna and propagation fields [1], [2]. There are two major advantages associated with EBG ground planes. First, such structures exhibit the possibility of creating a perfect magnetic conductor (PMC) because of their in-phase reflection phase characteristics. Thi...
متن کاملHigh Levels of Circular Polarization
We present multi-frequency, high resolution VLBA circular polarization images of the radio source 3C 84 in the center of NGC 1275. Our images reveal a complex distribution of circular polarization in the inner parsec of the radio jet, with local levels exceeding 3% polarization, the highest yet detected with VLBI techniques. The circular polarization changes sign along the jet, making 3C 84 als...
متن کاملDual Band Dual Polarized Slot Cut modified Circular Microstrip Antenna
A new broadband and dual band circular slot cut modified circular microstrip antenna is analyzed and proposed. The parametric study to analyze the effects of circular slot which realizes broader bandwidth is presented. The circular slot creates two additional resonant modes near the fundamental TM11 mode resonance frequency of the equivalent circular patch and yields bandwidth of 202 MHz (8%). ...
