Introduction to radio and radio antennas
IEEE Spectrum, 1971Electromagnetic wave propagation is a simple and beautiful phenomenon, but its rigorous mathematical derivation from Maxwell's equations is formidable. This article makes many of the concepts visible and plausible using only mathematics available to college freshmen and taught today in most high schools.

2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015
The average smart phone user picks up the device 1,500 times a week. Wireless communication appears to be taking over our lives but it also presents interesting challenges to RF designers. This paper contends that the mobile terminal will emerge as a central command post for most of our daily affairs and will therefore sustain an increasingly heavier ...

Radio Engineering: From Software Radio to Cognitive Radio
2011Software radio ideally provides the opportunity to communicate with any radio communication standard by modifying only the software, without any modification to hardware components. However, taking into account the static behavior of current communications protocols, the spectrum efficiency optimization, and flexibility, the radio domain has become an ...
