Abstract: The present invention discloses an antenna tuning system and method thereof. The method comprises the following steps: choosing a parasitic antenna that combined with a main antenna, the strongest received signal strength indicator of a target station is detected; controlling the selected parasitic antenna that combined with a main antenna, to generate a scattering resonance through turning on or off a switch unit; and controlling a diffraction radiation pattern between the main antenna and the selected parasitic antenna through adjusting a load of a designed circuit.

Abstract: An antenna system comprises first and second support structures, and a plurality of first, second and third antenna elements. Each of the first and second support structures has four sides. Two adjacent sides are perpendicular to each other so that both the first and second support structures form a closed loop. The first support structure is disposed outside of and surrounds the second support structure. Some first antenna elements are disposed on two symmetric sides of the first support structure, and other first antenna elements are disposed on two symmetric sides of the second support structure. Some second antenna elements are disposed on another two symmetric sides of the first support structure, and the other first antenna elements are disposed on another two symmetric sides of the second support structure. The third antenna elements are disposed on the four sides of the second support structure.

Abstract: The present invention discloses an antenna apparatus. The antenna apparatus includes a first antenna array and a second antenna array. The first antenna array includes multiple first radiating elements for transmitting radio signals of a first frequency. The second antenna array includes multiple second radiating elements for transmitting radio signals of a second frequency, wherein the first and second radiating elements are arranged in a staggered manner; wherein each of the first radiating elements is disposed between two of the second radiating elements; and wherein each of the second radiating elements is disposed between two of the first radiating elements.
