A foldable dual linear polarized antenna with gamma match at L band is presented. Two crossed dipoles are fed by two feed networks with gamma match to achieve the two polarizations. Since the gamma match uses the ground in the center of the radiator, it is relatively easy to extend the conventional single polarization to dual polarization. The feed networks are printed on two sides of a rigid PTFE substrate, while the radiators are printed on one side of flexible copper cladded polyimide substrate. Taking advantage of feed network’s planar configuration and the use of flexible substrate, the dualpolarized
antenna can be folded with low profile. Thus the proposed dual polarized dipole antenna is a good candidate for L-band space applications where the antenna must be stowable and deployable.
