In recent years we have seen the emergence of commercial applications at high frequencies, such as the top part of the microwave band and the millimeter and sub-millimeter bands, and it is expected a big increase in the coming years. This growing demand requires a rapid development of low-cost technology with good performance at these frequencies, where common technologies, such as microstrip and standard waveguides, have some shortcomings. In particular, existing solutions for high-gain planar scanning antennas at these frequencies suffer from the disadvantages of these technologies giving rise to high-cost products not suitable for high volume production. This book, therefore, provides, on one hand, the study of a new proposal to improve existing solutions to date for low-cost high-gain planar scanning antennas at high frequencies, and on the other, the study of new quasi-TEM waveguides that are more appropriate than current technologies for the realization of circuits and...
