MICROSTRIP PATCH ANTENNA WITH HIGH GAIN AND WIDE BAND CHARACTERISTICS

摘要

PURPOSE: A micro-strip patch antenna with high gain and wide band characteristics is provided to obtain a broadband and high gain by using a stack slot in a single patch and a stack patch. CONSTITUTION: A feed line(103) is extended a first direction in a dielectric layer. An air cavity(109) is installed in lower part of the feed line. A first slot(205) is extended to a second direction different from the first direction on the top of the feed line circuit. A second slot(306) is overlapped with the first slot and is extended to the second direction. A patch antenna(402) is arranged on the top of the second slot.
