In order to meet broad-beamwidth demand of missile-borne antenna, a new multi-polarization antenna was designed. The antenna contains two ports working with linear and circular polarization, so that it can receive three orthogonal components of electric field in space. Linear and circular polarizations are realized by a circular patch and monopole antenna loaded by a disc respectively. Copper poles are added between circular patch and disc to adjust the matching of monopole antenna. The measurement results show that impedance bandwidth in which return loss is less than 40dB are 1.21 ~1.85GHz and 1.54~1.61GHz for linear-polarization and circular-polarization ports respectively. The bandwidth for axial ratio (AR) <3dB is 1.45 ~ 1.8GHz. The isolation between two ports is larger than 15dB. The antenna can be used as missile-borne antenna for its advantages of compact structure and low profile.
