  • Super thin, cavity free spiral antenna
    Patent number: 6407721
    Abstract: A super thin, cavity free spiral antenna includes a radiating element having a first spiral arm and a second spiral arm formed on a front surface of a first dielectric substrate. In addition, the antenna includes a resonant ground plane formed on a back surface of the first dielectric substrate. From the perspective of the radiating element, the resonant ground plane appears as a back ground plane which is further away from the radiating element than in actuality. As a result, operation in the microstrip mode is provided even without a cavity.
