Custom 2-D and 3-D Antenna

Model shielding enclosure using custom 3D shapes and analyze electromagnetic interference due to slots or apertures in enclosure excited by interior sources.

Model and analyze a spherically capped biconical antenna using custom 3-D shapes. This antenna is a canonical broadband radiator used in practical ultra-wide-band communication systems. [1] The two cones of the antenna are connected by a cylindrical delta gap feed. The height and diameter of the cylindrical feed are equal. The location of the feed is chosen in between the two cone apex points as the gap between them can be considered as infinitesimally small, which nearly resembles an ideal antenna. Later, the effect of feed dimensions variation and mesh density variation near the delta gap is studied by comparing the antenna input impedance for two different feed diameters and mesh density. The antenna is analyzed in the frequency range of 900MHz to 15GHz.

Analyze the performance of a U-shaped monopole antenna designed on a PCB and mounted on a conical ground. You achieve low-frequency matching by inserting a trident inset feed. The conical ground with an elliptical shape at the base of the radiator outperforms traditional UWB monopole designs in impedance-matching bandwidth and radiation pattern omnidirectivity [1].

Analyze the performance of a delta loop antenna over a metal ground. The length of the antenna is λ/3 on each side of the triangle, where λ is the wavelength. Equilateral delta antennas are single-band high frequency (HF) antennas. You vary the baseline parameters of an antenna such as the length and height above the ground to optimize antenna performance [1].

Analyze the performance of an edge-wall slotted waveguide array antenna. These antennas have many advantages, including high gain, high power handling capacity, and easy manufacturing [1].

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.

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.

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.
