Custom 2-D and 3-D Antenna

Stereolithography files, custom 2-D meshes, 2-D geometry, geometrical shapes, mathematical operators

Create your own customized antenna by importing a planar mesh. For more complex 2-D structures, use 2-D shapes provided in the Antenna Toolbox™ and perform Boolean operations on them. The resulting shape can be a 2-D antenna, or it can be describe a specific layer in the PCB stack.

To author 3-D antenna geometry, Use Stereolithography (STL) files. Define the feed for this arbitrary element and analyze the antenna or array using existing analysis functions.

Featured Examples

Import and Analyze Custom 3-D Antenna Geometry

Simulate a 3-D custom antenna geometry from an STL (stereolithography) file. To simulate a 3-D custom antenna geometry, use the customAntennaStl object. This object allows the user to simulate a custom 3-D geometry from an *.stl file. An STL file is a tessellation of a structure in 3-D space using triangles.

RFID Antenna Design

Creates a commercially available RFID tag operating at 915 MHz. The planar antenna is drawn and meshed using PDE Toolbox™. The meshed structure is then imported into Antenna Toolbox and solved for its EM properties.

Double-Slot Cavity Patch on TMM10 Substrate

Create a custom slot cavity patch using custom antenna geometry and thick dielectric substrate. A double slot cavity patch consists of a double slot patch, backed by a cavity and probe-fed. The cavity is filled with TMM10 substrate. The cavity backing helps to reduce back radiation. You can use this antenna for microwave imaging by placing the antenna close to the human body.
