A partially shorted microstrip antenna configured to wrap around a projectile's body without interfering with the aerodynamic design of the projectile. The microstrip antenna has three identical conformal antenna elements equally spaced around the circumference of the projectile's body. The antenna has an operating frequency of 231.0 MHz.+-.400 KHz. Each antenna element includes a plurality of vias which operate as a partial short connecting the radiating element to the ground plane and thereby increase the bandwidth of the antenna element.
