Example 3: Vivaldi Antennas By RFSPACE

Our antenna testing service came across these great broadband antennas. The company RFSPACE offers a range of interesting Vivaldi broadband directional antennas at reasonable prices. The Vivaldi is often a planar (flat) antenna with a tapered gap that changes gradually from a transmission line at the feed point to a radiating structure. They are a beautiful organic shape and are named after the horn shape used for centuries in “wind” musical instrument.

Model TSA600 (Specified from 600-6000 MHz)

We have run a 2D polar plot test program on the RFSPACE model TSA600 PCB Vivaldi antenna from 300 to 6000 MHz in 10 MHz steps (for a total of 571 patterns). You can download the results spreadsheets containing all of these gain measurements and templates for plotting the 2D polar data. This is the same format that all of our customers get for 2D polar patterns. The enlargeable pictures below show the anechoic chamber setup and the results graphs. Download the data file set (Excel results with graphs and 2D plot tabs).

Model UWB1 (Specified from 430 MHz to 6 GHz + )

We have run a 2D polar plot test program on the RFSPACE model UWB1 aluminum Vivaldi antenna from 300 MHz to 20 GHz in 851 steps (patterns). This is a great performing inexpensive wideband antenna, useable from 400 MHz to 13 GHz. You can download the results spreadsheets containing all of these gain measurements and templates for plotting the 2D polar data. This is the same format that all of our customers get for 2D polar patterns. The enlargeable pictures below show the anechoic chamber setup and the results graphs. Download the data file set (Excel results with graphs and 2D plot tabs).
