Patent ID: 8854270

Claim:
A hybrid multi-antenna system, comprising: a system circuit board, having at least a system ground plate located thereon, wherein the system ground plate is served as a reflector of the hybrid multi-antenna system; an antenna substrate, wherein the antenna substrate and the system ground plate have a first distance therebetween; at least a dipole antenna, providing a first operating band, and comprising a first signal feed-in source; and at least a monopole-slot antenna, providing a second operating band, and comprising: a second signal feed-in source; a radiating conductor sheet, having a first side and a second side, wherein the second side is opposite to the first side; and a slot, having an open-end, a first long side, and a second long side, wherein the second long side is opposite to the first long side, the open-end of the slot is located on the first or second side, a length of the slot is about 0.25 wavelength of a central frequency of the second operating band, the second signal feed-in source is disposed on the radiating conductor sheet, one end of the second signal feed-in source is electrically connected to the first long side, and the other end of the second signal feed-in source is electrically connected to the second long side; wherein the dipole antenna and the monopole-slot antenna are located on a same surface of the antenna substrate, the monopole-slot antenna and the dipole antenna have a second distance therebetween, and the first signal feed-in source and the second signal feed-in source are perpendicular to each other, and have a phase difference of 90°.
