摘要
Based on the super-resolution property of time reversal electromagnetic wave far-field focusing, a subwavelength antenna array is proposed. The elements of the array are etched into those that have microstructures, placed at an interval of lambda/20 apart from one another, and have independent channels. Compared with the subwavelength antenna arrays, each of which is composed of other microstructure elements, the array, whose radiation property of individual antennae is similar to others, shows better super-resolution characteristic of far-field focusing. Therefore, an effective wireless terminal antenna array is provided for the high-speed and high-quality multiple-antenna communication using the time reversal technology.
