Abstract

This work proposes a design of novel magnetically tunable substrate integrated waveguide (SIW) slot antenna with one ferrite slab loaded in the antenna. The operation frequency of the antenna can be tuned more than 380 MHz in the X-band from 9.32 to 9.70 GHz when the bias magnetic field changes from 0 to 0.12 tesla. Within the tunable frequency range, antenna gain is more than 6 dBi. The radiation patterns and the gain are almost not affected by the changing of applied magnetic field, showing a good high gain antenna with frequency tunable feature.
