Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss and reflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line ...

Voltage Standing Wave Ratio (VSWR) is a measurement of the impedance match of any RF component, subassembly, instrument in reference to a standard 50-Ohm resistive impedance. It is generally expressed ...

If you have ever operated any sort of transmitting equipment, you’ve probably heard about matching an antenna to the transmitter and using the right co-ax cable. Having everything match — for example, ...

Knowing the directivity specification of your measurement device can go a long way in setting measurement expectations. Directional power measurements are important when determining transmitter output ...

A novel design of a dual-polarized broadband 2-18GHz horn antenna with VSWR (Voltage Standing Wave Ratio) less than or equal to 2.2 is presented. The designed horn antenna is most suitable as a feed ...
