Radioengineering Volume 20, Number 2

For the last 20�years, the Radioengineering journal quarterly has been publishing original scientific and engineering papers from the area of radio engineering and science.The nature of the Radioengineering journal is interdisciplinary. This journal is interested in covering a wide area of radio electronics starting from applied electromagnetism, wave propagation and antennas, continuing to high-frequency circuits and optoelectronics, and finishing with signal processing and multimedia, wireless communications and telecommunications and finally biomedial engineering topics. The journal can, therefore, present a wide view on all aspects of today's�radio engineering and science, initiate a mutual inspiration between disciplines; and support their cohesion in the frame of complex radio electronic systems.
