Abstract:
A broadband telemetry antenna for use on a projectile comprising:a ground plane adapted for mounting on said projectile; a dielectric substrate positioned above said ground plane, said dielectric substrate having an upper surface and a lower surface, said dielectric substrate being configured as a circle; and a microstrip antenna spaced apart from and electrically separated from said ground plane by said dielectric substrate, said microstrip antenna being tuned over an S-Band Frequency range of 2.2 to 2.3 GHz; said microstrip antenna including: a circular shaped radiating patch mounted on the upper surface of dielectric substrate for transmitting an RF (radio frequency) signal having telemetry data contained therein; and a filter mounted on the lower surface of said dielectric substrate, said filter being electrically connected to said radiating patch to filter GPS (Global Positioning System) signals from the RF signal transmitted by said radiating patch.
