Abstract

This Modified Self-complementary LPDA [1] has a second array of dipoles so arranged that each dipole of the second array has a quarter-wavelength phase difference from that of the corresponding dipole of the standard LPDA array for the given radiation field. The cross-element LPDA does not need a broadband 90-degree hybrid junction to produce circular polarization.
