Radiation Properties of Multiband Circular MSA with Half-Ring Slots
Novel multiband circular microstrip antennas (C-MSAs) with multiple half-ring slots are presented in this paper. Two antennafeeding systems, i.e. an embedded L-probe beneath the patch and a coplanar circular arcshaped probe (T-probe), are used to feed the C-MSA with multiple half-ring slots. The embedded L-probe is used to excite the CMSA with a double-layer dielectric substrate due to its trem...
متن کاملImpedance bandwidth optimization of double slots circular patch antenna using genetic algorithm and the Interface Fuzzy Logic
A modified circular patch antenna design has been proposed in this paper, the bandwidth of this antenna is optimized using the genetic algorithm (GA) based on fuzzy decision-making. This design is simulated with HP HFSS Program that based on finite element method. This method is employed for analysis at the frequency band of 1.4 GHz- 2.6 GHz. It gives good impedance bandwidth of the order o...
متن کاملMultilayer Circularly Polarized Circular Annular Ring Patch
This paper presents the effect on circular polarization of multilayer circular annular ring patch (CARP). A CARP have been fabricated on FR4 substrate of dielectric constant 4.2 and thickness 1.52mm. Experimental resonant frequency impedance bandwidth and Axial ratio of simple CARP, covered CARP, spaced dielectric CARP and CARP with two superstrates have been measured and simulated using full w...

متن کاملAnalysis of Single Square Ring Reflectarray Element for Bandwidth Enhancement
An analysis of phase variation and phase range of single square ring element for broadband reflectarray antenna is presented in this paper. The analysis and design of reflectarray antenna element is presented based on variable size of the square ring element parameter a t X-band and Ka-band. The design procedure and critical parameters are also discussed. Modifying the current distribution of s...
