This paper proposes an antenna suitable for projectile telemetry applications. The operating frequency of the ceramic patch antenna currently used for projectile applications can easily be shifted out of the desired frequency range due to the very narrow bandwidth of the ceramic patch. The proposed antenna consists of a printed and inverted triangular monopole, a sleeve and a ground plane. Antenna performances according to design parameters are analyzed from which optimum dimensions of the antenna are derived. The sleeve monopole is realized on an FR-4 substrate of 10mm width and 30㎜ height and placed at the center of a ground plane of 28㎜ diameter. Measurements of the fabricated antenna show favorable performances such as a 3.74㏈i maximum gain, a reflection coefficient less than -10㏈ over 1.62-3.25㎓ and an omnidirectional azimuth pattern.
