Abstract

The paper reports a new phenomenon of space synchronism of electromagnetic waves propagating in a transmission line and magnetostatic waves excited in a ferrite layer (film). This synchronism results in the extremely narrow (less 1/spl deg/) radiation pattern of magnetostatic wave antennas and in the unidirectional propagation of wave beams at certain frequencies. Calculations were performed for microstrip antennas in the frequency band of surface magnetostatic waves. Application of the effect is suggested for tunable microwave multichannel filters and for space filtering of magnetostatic waves.
