- Abstract
- A low-profile, broadband 2×2 planar array constructed only of metal is proposed for space applications. The single element of the array is capable of generating circular polarization with a non-symmetrical (with respect to broadside) radiation pattern. Sequential rotation is introduced at the array level to correct the asymmetry of the beam and for improving the polarization purity. The resulting antenna radiates at broadside with a 12.5 dBi gain and impedance bandwidth of 18.22 %. Its overall size is 1.42λ×1.42λ×0.2817λ . The total volume of the antenna is 1.0961×10−5m3 and the total weight is estimated at 42 g. It has been shown that the product gain-bandwidth is competitive as compared to available solutions in the literature.
