Established in 1968  the group has comprehensive experimental facilities housed in the Antenna Measurement Laboratory, which has recently received £1 million in infrastructure investment. The group has strong links with industry and a current active grant portfolio of over £7.5m and this includes a prestigious EPSRC platform grant valued at £1.2 million to fund post-doctoral researchers as well as in- reach and outreach activities with other world-leading antenna laboratories and EPSRC Programme Grant led by Prof. Yang Hao on Quest of Transformational Electromagnetics worth around £4.6m.

  • Our research on antennas for mobile communications includes multiband antennas, multiple antennas for MIMO applications, Ultra wideband (UWB) antennas, semi-smart base station antennas and antennas and radio propagation for body-centric wireless communications.
  • In the area of metamaterials we study computational electromagnetic models for both active and passive structures. We are studying new nano-materials such as graphene and carbon nanotubes that offer possible advances in antennas and metamaterials. 
  • We are developing software techniques to exploit the concepts of Transformation Electromagnetics, offering such novel devices as flat multi-reflector antennas and cloaking devices. 
  • Our research on Terahertz Spectroscopy aims to help scientists visualize structures such as proteins and actively enhance chemical reactions.
  • In the area of antennas and healthcare we study the interaction of electromagnetic waves with biological tissue, dosimetry, wireless implants and RF sensors for example in blood glucose monitoring.
  • We also apply CEM to Microwave Electron Tube Devices to understand design of magnetrons with the aim of developing compact high power millimetrewave sources.  
  • In the area of metrology we work on near-field measurement, millimetrewave imaging for security and compact antenna test range development.

The Antenna Measurement Group's mission statement is "High Quality Research backed up by High Quality Measurements". Comprehensive experimental facilities are available at Queen Mary and are housed in the Antenna Measurement Laboratory. Research in the Laboratory is directed by Prof. Clive Parini (FREng) along with 5 full time members of academic staff and assisted by 4 part-time Research Professors (see People).

 

Research Activities

The Antennas & Electromganteics research group has a strong team of acadmics and researchers working on various areas realted to antenna engineering, bio-electromagnetics, novel materials for enhanced performance and antenna & Em theory and metrology concepts. The group has established excellent collaborations and links with many academic and industrial partners working specifically inon antennas and EM problems but also ranging to problems for wireless communications and medical applications.
