Abstract:
1. A TM microstrip antenna adapted for use on a projectile comprising: (a) first, second and third rectangular shaped 120-degree TM microstrip antenna elements mounted on an outer surface of said projectile adjacent to one another, each of said first, second and third 120-degree TM microstrip antenna elements including: (b) said first, second and third 120-degree TM microstrip antenna elements generating an omni-directional radiation pattern at the front and rear of said TM microstrip antenna at first and second operating frequencies; and (c) said first, second and third 120-degree TM microstrip antenna elements being driven by equal amplitude signals which are progressively phase shifted by one hundred twenty degrees to obtain circular polarization of the electromagnetic filed generated by said TM microstrip antenna.
