Abstract: PURPOSE: A microstrip patch antenna is provided to broaden frequency bandwidth, improve antenna gain, and easily execute an impedance matching by using a stack slot. CONSTITUTION: A microstrip patch antenna comprises a dielectric layer, a feeder circuit, at least one slot(205), and a patch antenna(402). The feeder circuit is arranged inside the dielectric layer. The slot is arranged inside the dielectric layer in order to be separated from the feeder circuit. The patch antenna is arranged outside the dielectric layer in order to be separated from the slot. The dielectric layer includes a plurality of LTCC(Low Temperature Co-fired Ceramic) substrates, a plurality of silicon substrates, a plurality of printed circuit boards, and a plurality of liquid crystal polymer substrates.

Abstract: 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.
