Wideband Antipodal Vivaldi Antenna (AVA) loaded with dielectric lens for fifth generation gigabit communication and millimeter-wave (MMW) imaging system is presented. The simulated results demonstrated that proposed antenna can be operated from 10 GHz up to 65 GHz band showing 146% fractional bandwidth. The designed antenna is considered for transmission of short time duration pulses covering 27–33...
In this paper, the authors present a novel DRA/microstrip hybrid high gain and circularly polarized antenna for MMW applications. It consists of a printed rectangular patch with a shaped corners and a hollow rectangular DR radiator works together as a single antenna element fed by a rectangular aperture in the ground plane.
In this paper the triangular shaped microstrip power divider is designed for C-band operation using Defected Ground Structure (DGS). Calculations are carried out using different simulation tools based on different numerical techniques. Good agreement is found between the calculated results using both HFSS and CST MWS. A parametric study has been carried out to address the effect of DGS parameters...
In this paper, numerical investigation of band rejection capabilities of UWB elliptical slot antenna with circular and crescent shaped radiators are presented. The band rejection performance can be achieved either by a C-shaped slot in the ground plane design A or by cutting a C-shaped slot in the microstrip feedline design B. The calculated VSWR of the both antenna designs show an impedance bandwidth...
