AB  - This paper presents dual-band high-gain subwavelength cavity antennas with 
      artificial magnetic conductor (AMC) metamaterial microstructures. We developed an 
      AMC metamaterial plate that can be equivalent to mu-negative metamaterials (MNMs) 
      at two frequencies using periodic microstructure unit cells. A cavity antenna was 
      constructed using the dual-band AMC metamaterial plate as the covering layer and 
      utilizing a feed patch antenna with slot loading as the radiation source. The 
      antenna was fabricated with a printed circuit board (PCB) process and measured in 
      an anechoic chamber. The |S(11)| of the antenna was -26.8 dB and -23.2 dB at 3.75 
      GHz and 5.66 GHz, respectively, and the realized gain was 15.2 dBi and 18.8 dBi 
      at two resonant frequencies. The thickness of the cavity, a sub-wavelength 
      thickness cavity, was 15 mm, less than one fifth of the long resonant wavelength 
      and less than one third of the short resonant wavelength. This new antenna has 
      the advantages of low profile, light weight, dual-frequency capability, high 
      gain, and easy processing.
