The author presents small antennas that exploit a new class of slow-wave modes. These modes were originally observed in anisotropic volumetric media and were recently realised using a pair of coupled microstrip transmission lines (TLs) printed on a uniform substrate. The simplicity of the coupled printed lines and slow-group velocity of the photonic crystal modes provided an avenue for designing small conformal antennas. The author reviews the degenerate band edge (DBE) mode antennas and extends their bandwidth by supporting dual resonances. This is done by inserting lumped elements along and between the printed TLs. The resulting coupled double loop (CDL) antenna has 14.7% bandwidth and is as small as λ0/9.8×λ0/9.8 (λ0/16 thick) in footprint. Alternatively, magnetic photonic crystal (MPC) mode is realised using the same DBE-printed structure and by inserting small ferrite sections within the otherwise uniform substrate. This new MPC antenna was realised on a high-contrast (ɛr=10.2) dielectric section and attained a gain of 3.1 dB (73% efficiency) and 8.1% bandwidth on a footprint as small as λ0/9.8×λ0/10.4 (λ0/16 thick).
