We study the radiation properties of electrically small resonant antennas (k a < 1) composed of electric-field-coupled (ELC) and complementary electric-field-coupled (CELC) resonators and a monopole antenna. We use such parasitic ELC and CELC "metaresonators" to design various electrically small antennas. In particular, monopole-excited and bent-monopole-excited CELC resonator antennas are proposed that provide very low profiles on the order of λ 0 / 20. We compare the performance of the proposed ELC and CELC antennas against more conventional designs based upon split-ring resonators. © 2013 American Institute of Physics.
