Design of a dual-band conformai antenna on a cone surface for missle-borne

In this paper, a conical conformai antenna array operating in the Beidou B3 band and the GPS L1 band is proposed. The upper end of the antenna patch is shorted to the missle body to form a shorted wall for miniaturization. And an open stub is loaded to realize dual-frequency resonance. The patch is attached to a conical surface and wrapped to the missle body. The antenna element with good performance is rotated by 180 degrees to obtain a conforma! antenna array containing two units. The two elements are feed in equal amplitude and phase with the coaxial line. Finally, the proposed antenna array shows an omnidirectional radiation characteristic in the azimuth plane and the gain patters in the elevation plane are show as "8" fonts.
