A novel compact active BeiDou helical antenna, operating at normal mode is proposed for high-shock projectile applications. To achieve excellent impedance matching, a grounded matching stub is introduced in this design. For demonstration, a prototype with extremely compact size (22×22 mm) is fabricated and measured. The measured reflection coefficients below 10-dB is almost 15 MHz centered at 1268 MHz. Omni-directional radiation pattern of the proposed antenna is realized. Additionally, stable signal reception under various motion attitudes could also be proved by experiments.
