Abstract
A micro-strip antenna includes an L-shaped coupler, a set of micro-strip antennas, and an L-shaped band-stop filter. The set of micro-strip antennas includes at least one rectangular micro-strip antenna unit and a micro-strip line. The rectangular micro-strip antenna unit is coupled to the micro-strip line. The micro-strip line is coupled to the first end of the coupler. The band-stop filter is disposed along a corner of the rectangular micro-strip antenna unit, and is disposed between the antenna unit and the coupler without being physically connected to the antenna unit and the coupler. The width, length, and position of the L-shaped band-stop filter can be determined for the specific band-stop frequency and to optimize its coupling extent with the L-shaped coupler.
