Figure 6-15: Cross-polarized Vivaldi antenna (1.7 to 20
GHz) with two SMP connectors, mounted on a
special antenna fixture
This dual Vivaldi antenna can be used as a communication antenna, allowing to trans-
mit signals towards the DUT, and to receive signals from it.
In this context, typical DUTs include mobile communication devices based on, e.g.,
GSM-1800, GSM-1900, selected UHF, UMTS and LTE bands, Bluetooth, Wi-Fi, Zigbee
and similar technology standards.
In combination with its fixture, the antenna can be flexibly mounted on the antenna
ring, as shown in Figure 7-56.
