Compact and Broadband Stacked Patch Antenna Loaded with Mushroom Metamaterials
A stacked patch antenna is proposed which is loaded with mushroom metamaterials. The metamaterials enable the antenna to resonate at a very low frequency while the stacked patches broaden the impedance bandwidth. A particular metamaterial antenna is demonstrated in full wave calculations. A broad bandwidth of 24.6% is achieved for such a compact antenna, of which the driven and parasitic patch lengths are kept very small at the order of 0.21λ and 0.25λ respectively (λ is the wavelength of center frequency in the working bandwidth). The antenna gain is observed to be 7.26dBi while the peak efficiency is over 96% in the numerical example. The proposed antenna is suitable to be used in the portable wideband communications.
