In this webinar,[ XFdtd's](https://www.remcom.com/xfdtd-3d-em-simulation-software) product team discusses group delay for UWB antennas.

In a laboratory setting, the group delay between two antennas is measured directly using a VNA. Typically, two identical antennas are separated by a minimum of the far-field distance and aligned such that the transmitter (TX) and receiver (RX) have both the same polarizations and look directions. The resulting group delay is a function of the TX antenna, the RX antenna, and the separation distance. In order to determine the group delay associated with a single antenna—either TX or RX—some analysis of the measured group delay must be performed.

**Key Takeaways:**

- Learn about the latest developments for computing [group delay](https://support.remcom.com/xfdtd/users-guide/antenna-design/antenna-group-delay.html) for an antenna.
- Explore how group delay is determined directly from a single-port simulation.
