Wire Antenna Simulation

This application note analyzes a basic coaxial antenna modeled as a quarter-wavelength section of coaxial cable operating from 2 to 4 GHz. Using EMWorks, you can compute return loss at the feed, visualize near- and far-field radiation patterns, and study how electromagnetic waves propagate inside the antenna structure and surrounding air region.

Learn how to model and simulate a 2.45 GHz axial-mode helical antenna in EMWorks, evaluate radiation patterns, gain, and matching, and optimize circular polarization for wireless and satellite communication applications.

This application note analyzes a car FM antenna in EMWorks over 60–120 MHz to cover all regional FM bands. It uses a fast sweep to evaluate return loss and far-field radiation at 90 MHz, showing an omnidirectional pattern and acceptable matching for in-vehicle FM reception worldwide

This application note analyzes a three-dipole Franklin collinear antenna operating near 3.2 GHz using EMWorks. The model uses Duroid 5880 substrates inside an air box and is simulated over 0.5–3.5 GHz to study return loss and near/far-field distributions. Results show good matching around 3.25 GHz and constructive radiation from the three aligned dipoles, confirming the expected gain and E-plane directivity of the collinear array.

Understand how implantable antennas are optimized for biotelemetry, ensuring safe and efficient data transmission from inside the body.
