Combining the expertise of many academics in the Microwave and Antenna Engineering Group in Heriot-Watt University, we are pushing the research forefront on integrated active arrays and various applications, including:

From technology aspects:

• Active array modelling, involving non-linear and memory effects;
• Linearisation techniques;
• Wideband, high-efficient power amplifier MMIC and circuit design;
• Channel precoding and equalisation involving transceiver non-reciprocal;
• Active array loadpull effect and its mitigation approaches;

From application aspects:

• Satellite multi-beam antenna systems;
• Cellular base-station antenna systems;
• Physical-layer wireless systems, including directional modulation and radio frequency fingerprinting;
