Custom Antennas
Create 2-D and 3-D antenna geometry with conductor and dielectric material properties using shapes. Import a 2-D mesh, boundary points data, or a CAD file to define antenna geometry. Define the feed for this arbitrary element and analyze the antenna by using analysis functions. Create layered PCB antenna from geometric shapes.

Functions
Featured Examples
Design and Analyze Perforated Horn Antenna for RF Applications
Design a perforated horn antenna suited for RF applications using 3-D modeling features of the Antenna Toolbox™.
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.
RFID Antenna Design
Design a commercial RFID antenna operating at 915 MHz. This example uses Partial Differential Equation Toolbox™ to draw and mesh the planar structure. The meshed structure is then imported into Antenna Toolbox™ and analyzed for its electromagnetic properties.
Import and Analyze Custom 3-D Antenna Geometry
Simulate a 3-D custom antenna geometry from an STL (stereolithography) file. An STL file is a tessellation of a structure in 3-D space using triangles. To simulate a 3-D custom antenna geometry, use the customAntennaStl object. This object allows you to simulate a custom 3-D geometry from an *.stl file.
PCB Antenna for USB Dongle and BLE Applications
Design and analyze a PCB antenna for USB dongle and BLE applications at 2.4 GHz.
Create Antenna Model from Gerber Files
Create an antenna model from Gerber files and subsequently analyze the antenna. The Gerber file format is used in printed circuit board (PCB) manufacturing and is defined in the RS-274X standard which is the newer extended Gerber format. The Antenna Toolbox™ supports the newer RS-274X format both to generate Gerber files from an antenna model as well as to create an antenna model from a set of Gerber files.
Antenna Model Generation and Full-Wave Analysis From Photo
Demonstrates the process of using a photograph of a planar antenna to generate a viable antenna model and its subsequent analysis for port, surface and field characteristics. The Image Segmenter app is used to perform segmentation on the image of an RFID tag, and the resulting boundaries are used to set up the antenna model in Antenna Toolbox™. An initial impedance analysis is done over a frequency range to understand the port characteristics of the antenna. After determining the resonant frequency, the current and far-field pattern are calculated and plotted.
