Antennas with beam control in radar technology

The book presents selected issues in the field of beam-controlled antennas on flat and cylindrical surfaces. Basic problems of the theory and practice of creating antenna arrays and their components such as: elementary radiators, broadband couplers, phase shifter and intersections of microstrip lines are discussed. Also presented is the methodology of designing the transceiver module, which is the basic element of the phase pattern with distributed power supply.
Monograph from the series: Modern radar technology is primarily addressed to radar system engineers, but every engineer specializing in very high frequency technology will find in it a discussion of the issues that interest him.
