A single-layer bidirectional antenna that provides circularly polarized (CP) radiation of the same sense in both of the hemispheres has been designed and evaluated. The concept is the combination of two identical endfire CP antenna elements in a back-to-back configuration. The design of each element is based on the superposition of two closely spaced complementary dipoles connected by phase delay...
Single layer single feed antenna with circularly polarized (CP) endfire radiation is proposed with superposition of two complementary dipoles. The half mode substrate integrated waveguide (HMSIW) serves as equivalent magnetic dipole, while the double side printed conductor arms act as electric dipole. To satisfy the required magnitude/phase relations between two dipoles for achieving CP characteristic,...
