Abstract:
A shorting-wall loaded metamaterial mushroom array antenna is proposed for bandwidth enhancement and compact design. Owing to the shorting-wall loading, the lower frequency region of the right-handed branch of the composite right/left-handed (CRLH) mushroom structure is exploited. The operating modes of the antenna are investigated. The antenna prototype at 5-GHz band exhibits 26% impedance bandwidth (|S11|<;-10 dB) with a compact size of 0.65λ0 × 0.61λ0 × 0.06λ0 (λ0 is the center operating wavelength in free space).
