MICROSTRIP PATCH ANTENNA WITH HIGH GAIN AND WIDE BAND CHARACTERISTICS

摘要

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.
