Microstrip Patch Antenna

Mirostrip patch antennas are among the most popular antennas, used in various application areas. Model building for this type of antennas can be done in two ways: in WIPL-D general-purpose 3D modeler and in the tool specialized for printed structures, AW Modeler. A simple microstrip patch antenna is simulated here. The simulated results are verified with measurements performed by WIPL-D staff. The antenna is printed on RT Duroid 5880 substrate of height 1.5748 mm and of complex permittivity
2.2(1-j 0.0004). The model is made on a finite substrate and over finite ground plane. The antenna is fed by a probe that is extended to a coaxial line which is included in WIPL-D Pro model... read more

Compact Multi-band Antenna for Wireless Applications

The aim of this application note is to demonstrate the possibilities of WIPL-D Pro 3D EM Solver regarding simulation of complex printed antennas in a wide-band. Also, the aim is to illustrate the simplicity of creating models of this type of antennas in the specialized tool, AW Modeler. The software takes into account the influence of a finite-size ground plane backing the antenna. The antenna is simulated in the frequency range between 0.5 and 3 GHz and is modeled as being printed on a dielectric substrate with εr = 4.4 and thickness of 1.6 mm. The antenna is fully modeled using AW Modeler, an add-on tool for easy general 3D EM modeling and quadrilateral meshing... read more

Log-Periodic Dipole Antenna

This application note presents how to model an LPDA
antenna in WIPL-D software suite. Simulation results at
different operating frequencies are also presented. A Log-Periodic Dipole Antenna with 52 printed dipoles
is created in WIPL-D AW Modeler and then simulated
in WIPL-D Pro. Due to symmetry of the LPDA
antenna, only half of the structure is simulated. The
antenna is printed on a 0.813 mm thick dielectric
substrate having dielectric permittivity of r=2.33.
Entire antenna is around 261 mm long and is placed
4.25 mm away from the metallic circle having a
diameter of 248 mm... read more
