The use of a rectangular dielectric resonator as an antenna element is reported. The resonator is excited in its lowest order magnetic dipole mode using a microstrip line-slot combination. Measured results on the proposed antenna configuration show that the antenna has a bandwidth of about 10% and that its far field pattern is similar to that of a magnetic dipole. The overall antenna configuration is small in size, and can be easily integrated with MIC's (microwave integrated circuits). The proposed configuration should be useful in applications such as active antenna arrays where the active circuitry can be fabricated on the same substrate. >
