Patent number: 10629993Abstract: The LTCC (Low Temperature Co-fired Ceramic) substrate is used to form an antenna structure operating at 60 GHz. The dielectric constant is high and ranges from 5 to 8. The substrate thickness is fabricated with a thickness between 360 ?m to 700 ?m. The large dielectric constant and large thickness of the substrate creates a guiding wave in the LTCC that forms an endfire antenna. A high gain signal of 10 dB in a preferred direction occurs by placing the microstrip fed dipole structure in the center of the LTCC substrate creating a dielectric cavity resonator. The creation of a slot in the LTCC substrate between the two microstrip fed dipole structures eliminates beam tilting and allows for the two microstrip fed dipole structures to reduce the coupling to each other thereby providing substantially two isolated endfire antennas. These antennas can be used as multiple receive or transmit antennas.Type: GrantFiled: July 19, 2012Date of Patent: April 21, 2020Inventor: HungYu David Yang
