WebAbstract—The contrawound toroidal helical antenna (CTHA), a novel low-profile antenna, is a bifilar antenna with four terminal connections. The two filaments of the antenna can be thought of as a two-wire transmission line whose resonances are determined by the boundary conditions present at the ends of the line. The CTHA is then approximated ... Web-----begin privacy-enhanced message----- proc-type: 2001,mic-clear originator-name: [email protected] originator-key-asymmetric ...
