Abstract:

A metal-insulator-metal (MIM) composite right/lefthanded(CRLH) series-mode zeroth-order resonant antenna(ZORA) optimized for the 24 GHz ISM band is presented and compared to a series-fed patch array (SFPA) antenna. The CRLH ZORA exhibits superior performances for relatively short lengths (< 3λ0) whereas the SFPA may performs better, depending on the specific design, when the length is very long (> 5λ0), so that the resonant antennas operate as leaky-wave antennas with a leakage factor proportional to the density of the radiators along the structure. To our knowledge it the first time that the leakywave operation of an electrically very large “resonator” has been explicitly identified. The ZORA is particularly recommended for average electrical sizes in the order of 2λ0, where it should be systematically superior to a SFPA.
