摘要
A multi-band antenna includes an S-band substrate; an S-band annular ring on the S-band substrate; an X-band substrate in the S-band substrate; and an X-band patch located in a center of the S-band annular ring and on the X-band substrate. The S-band annular ring includes a first upper surface, the X-band patch includes a second upper surface, and the first upper surface is planar with the second upper surface. The multi-band antenna includes a second pair of concentric patch antennas arranged in an annular configuration and stacked on the first pair of antennas. The second pair of antennas are placed on the same substrate and are electromagnetically coupled to the first pair of antennas to provide an extended bandwidth capability.
