LTCC (Low Temperature Co-Fired Ceramic) complementary antenna based on defected ground structure and wireless communication equipment

The invention discloses an LTCC (Low Temperature Co-Fired Ceramic) complementary antenna based on a defected ground structure and wireless communication equipment, the antenna comprises at least four layers of dielectric substrates and three conductor layers, each layer of dielectric substrate is an LTCC dielectric substrate, the three conductor layers are located in a space enclosed by the four adjacent layers of dielectric substrates, and the conductor layers are located in the space. Each conductor layer is printed between two adjacent dielectric substrates by using an LTCC (Low Temperature Co-Fired Ceramic) printing process, the three conductor layers form a complementary antenna through a half-wavelength sheet antenna based on a defected ground structure, a quarter-wavelength cross section antenna and an excitation feeder line, the half-wavelength sheet antenna is used as an electric dipole antenna, and the quarter-wavelength cross section antenna is used as a quarter-wavelength cross section antenna.
