Abstract: An antenna module is disclosed. The antenna module includes a circuit board and at least one antenna set. Wherein, the antenna set includes a driving antenna and a plurality of parasitic antennas. The driving antenna is formed on the circuit board, and the parasitic antennas are positioned with the driving antenna as a center on the circuit board. Whereby, the space occupied by the antenna module can be small, and beams of wireless signals radiated by the antenna module can be controlled.

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: A wireless network device includes an antenna array and a lobe interleaver. The antenna array includes a plurality of antenna elements with different squint angles. The lobe interleaver is coupled to the antenna elements and has a plurality of output lobe ports. The lobe interleaver divides and interleaves the radio signal of the antenna array with the same phase and the same power to generate a plurality of lobes with different squint angles. The number of lobes is twice the number of antenna elements.

Abstract: A communication apparatus includes a first communication module, a second communication module, an antenna module and a filtering module. The first communication module transmits and receives a first RF signal on a first channel. The second communication module transmits and receives a second RF signal on a second channel. The antenna module includes multiple antennas for transmitting and receiving the first and second RF signals. The filtering module is coupled between the first and second communication modules and the antenna module. The filtering module filters the first RF signal according to a first frequency response, and it filters the second RF signal according to a second frequency response to ensure the first RF signal and the second RF signal do not interfere with each other.
