Abstract :
A rigorous moment method is used to find the radiation properties of a center-fed microstrip dipole on a ferrite substrate. The radiation characteristics of a microstrip dipole, including input impedance, antenna gain, and radiation efficiency, as a function of dipole size, frequency, and the ferrite material characteristics are studied parametrically using a moment-method solution. It is demonstrated that the bias magnetic field can dynamically change the antenna characteristics.<>
