General Considerations about Approximations and Modifications of Self-Complementary Antennas

  • Yasuto Mushiake


According to the theory of the self-complementary antenna (SCA), the basic structures of this type of antenna consist of infinitely extended planar sheets of perfect electric conductors. In addition, in the case of stacked antennas, an infinite number of element antennas are arranged periodically. Therefore, the theoretically obtained self-complementary antenna can only be approximated by limited size of structure and limited number of element antennas, when this principle is applied to extremely broad-band practical antennas.
