Radio Systems: Engineering and Applications : Willford Press : 9781682856352 : 1682856356 : 20 Jun 2019 : Radio engineering is a subset of electrical engineering. It deals with the engineering of devices in the radio frequency spectrum, between 3 kHz and 300 GHz. Some of the devices that use radio waves include mobile phones, radios, wifi, etc. A radio communication system comprises of a transmitter and a receiver. It also requires an antenna for converting electric currents into radio waves and vice versa. The principles of transmission, modulation, wave propagation, resonance and demodulation are important aspects of radio systems. An understanding of electronic hardware design, antenna radiation and circuit board material are also crucial in radio engineering. The book aims to shed light on some of the unexplored aspects of radio systems engineering and the recent researches in this field. The various studies that are constantly contributing towards advancing technologies and evolut
