A novel subwavelength array is proposed. It is demonstrated experimentally that the array has super-resolution focusing property in the far-field zone and each element has an independent channel. With this kind of subwavelength array used in time reversal mirror, better super-resolution focusing result is achieved. The proposed subwavelength array may be useful in the applications of multi-antenna ultra-wideband (UWB) wireless communications. %K time reversal %K subwavelength %K antenna array %K super-resolution
