The microstrip antenna has two identical grounded quarter wavelength microstrip antenna elements positioned around the circumference of the projectile's body. The antenna has an operating frequency of 425 MHz ±375 KHz, a maximum diameter of ten inches and a maximum length of nine inches. The microstrip antenna outputs a pair of equal amplitude flight termination signals and produces a quasi omni-directional radiation pattern with linear polarization.
