At the core […]

How Does Beamforming Work in an Active Array Antenna?

Beamforming controls the relative phase and amplitude of multiple RF channels so that an active array can create, steer and shape its electromagnetic beam electronically. In an active array, beamforming is not an isolated algorithm function. It is tightly coupled with antenna elements, T/R modules, RF control circuits, system calibration and beam management software, forming […]

What Is G/T? Active Array Receive Sensitivity & System Noise Performance

Introduction to G/T Alongside EIRP, G/T is the most critical system-level performance parameter defining the receive capability of an active array antenna. While EIRP characterizes transmit power and radiation efficiency, G/T fully quantifies receive sensitivity, noise performance, and weak‑signal reception capability. G/T is defined as the ratio of antenna gain to total system noise temperature. […]

What is EIRP?

For active array antennas, EIRP and G/T are the two most critical system-level performance metrics. They fully define the core wireless capability of an active array: EIRP quantifies transmit radiation capability, while G/T characterizes receive system sensitivity. Together, these two parameters determine the practical communication performance of active array systems in satellite communications, wireless links, […]
