FOLDED DIPOLE, FOLDED DIPLE MODULE, ARRAY ANTENNA AND MULTIPUL INPUT MULTIPUL OUTPUT ANTENNA

摘要

A cross dipole, a cross dipole module, an array antenna, and a multiple input multiple output antenna are provided to perform the multi-input and multi-output function by independently driving a plurality of array antennas. A cross dipole(100) comprises feeding points(111,112,113,114), basis dipole elements(121,122), the first parasitism dipole elements(131,132), and a switch(SW1). The feeding point is the terminal applying the signal to the cross dipole. The feeding point applies the signal to the dipole of the first direction. The feeding point applies the signal to the dipole of the second direction. The basis dipole element comprises a dipole of first direction(DP1) and a dipole of second direction(DP2). The switch selectively determines the first parasitic dipole element.
