Antenna Return Loss by VNA

Antenna Return Loss by VNA

The upper left graph illustrates the measurement of a filter with two ports at the Vector Network Analyser (VNA). Port 1 is feeding the device under test and is measuring the reflection. Port 2 is measuring the received energy. The lower right graph is showing a typical return loss measurement of an antenna. Has this […]

Antenna gain and beam angle

Parameters of antennas In addition to the mechanical dimensions and the type of connection, data sheets for antennas specify various electrical and physical parameters. 1. Antenna gain The antenna gain is a relative quantity that refers to a reference antenna. The reference value is the receiving field strength of the selected antenna in receiving direction […]

What is akorIoT?

akorIoT Micro & Nano was world’s first NB-IoT adapter with the freedom to select other cellular radios out of a range of modules without a SIM lock. You can also select any MCU kit with an Arduino compatible R3  or Nano expansion slot.  “akor” is the Proto-Celtic word for “open” akorIoT was the world’s first […]
