Active transmitting phased antenna arrays
IEEE Transactions on Aerospace and Electronic Systems, 2005The benefits of using transmitting phased array antennas for radar systems are examined. Accurate performance prediction for the transmitting phased array antennas requires theories describing both the antenna system and the power generation devices.

Ultra-wideband phased antenna arrays
DIPED - 2001. Proceedings of 6th International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (IEEE Cat. No.01TH8554), 2002A new type of ultra-wideband nonuniformly spaced antenna array is designed. So-called modified FCAA can work at a frequency band of up to 10:1. Under multiple frequency change the FCAA ensures the uniqueness of the main lobe in the space, constancy of the peak sidelobe level and directivity.

Simulation of phased array antennas
Tenth International Conference on Antennas and Propagation (ICAP), 1997This paper gives an overview of a computer simulation suite PHASAR which has been in use and under continuous development at Roke Manor. The program is written in FORTRAN and was originally produced to aid the design and testing of the then joint Plessey/MOD phased array radar demonstrator, MESAR.
