Antenna Interconnect & Impedance
Unigen has pre-qualified antennas that integrate the connectors, transmission line and the antenna.
UGWAS82 requires the use of a ½ dipole, 2.4~2.5GHz frequency range, with a VSWR no greater
than 2.0 and having a maximum output no greater than +2dBi The transmission line must be
designed to be 50-Ohm impedance.
Physical Implementation
The physical implementation of the RF transmission line must conform to the following
guidelines:
• Coaxial Cable: A coaxial of varying length may be used providing the impedance
measures 50 +/- 2 ohms and is non-radiating. Best practice RF engineering suggests
the cable should be kept to the minimum length required to satisfy the application.
Excessive cable and interconnect loss may adversely effect the effective transmission
and reception range of the end product.
