Claim 0:
1. A multi-input multi-output antenna system, comprising:
a metal plate;
a scanning antenna located on the metal plate and configured to detect at least one radio-frequency signal in a scanning area;
a plurality of working antennas located on the metal plate, each spaced apart from the scanning antenna; and
an isolator module mountable to the metal plate and comprising a plurality of isolators arranged annularly to form an isolated space surrounded by the isolators, wherein the isolator module is located between the working antennas and the scanning antenna such that the scanning antenna is in the isolated space and the working antennas lie outside of the isolated space,
wherein each of the isolators comprises a dielectric substrate, a metallic patch located at a top surface of the dielectric substrate, a grounding layer located at a bottom surface of the dielectric substrate and connectable to the metal plate, and a metal post penetrating the dielectric substrate and having a top end connectable to the metallic patch and a bottom end connectable to the grounding layer, and the dielectric substrate of each of the isolators is integrally formed with each other as a single unit; and
wherein the isolators are arranged as an inner ring and an outer ring adjacent to and surrounding the inner ring.
