A Novel Cylindrically Conformal End-fire Antenna Array Application on Missile

This paper presents a novel cylindrically conformal end-fire antenna array, which has 8 elements in the VHF frequency band. The proposed antenna array can be widely used in missile borne data transmission system. The novel broadband E-type PIFA element with absorbing material is designed and manufactured and it is powered by Wilkinson power dividers. By adjusting the length of phase shift, the radiation pattern towards the missile axis is realized. It achieves a 2-VSWR bandwidth of 26%. The end-fire radiation pattern has an acceptable shape and has a gain greater than 5dBi over the entire operating frequencies. It can be widely used in missiles.
