Patent number: 8270847Abstract: Polarization multiplexing with different differential phase shift keying (DPSK) schemes generally uses DPSK modulated signals modulated using different DPSK modulation schemes and combined with orthogonal polarizations relative to each other. The different DPSK modulation schemes may use different DPSK phase shifts to represent data, such as a regular DPSK modulation scheme and a ?/2 DPSK modulation scheme. By using different DPSK modulation schemes to represent data on the orthogonally polarized signals, the DPSK demodulators may effectively separate the orthogonally polarized signals using the property of the DPSK receivers. To optimize performance, the DPSK modulated signals may also be bit-interleaved when combined with orthogonal polarization.Type: GrantFiled: February 2, 2009Date of Patent: September 18, 2012Assignee: Tyco Electronics Subsea Communications LLCInventors: Hongbin Zhang, Jin-Xing Cai

Patent number: 8248319Abstract: A broadband circularly-polarized spidron fractal antenna is disclosed. The broadband antenna of the present invention can realize a bandwidth exceeding 70% without using a multilayer substrate to implement the broadband properties, by forming a geometric structure of a slot, i.e., a spidron fractal, which has not been used in the conventional antennas, on the ground surface of the antenna. The present invention can also induce the radiation properties of a circularly-polarized wave from the properties of the spidron fractal shape, without employing an additional secondary circuit such as a phase distribution circuit for implementing the circularly-polarized wave. Due to such properties described above, the present invention can implement a small broadband circularly-polarized antenna that costs less to manufacture.Type: GrantFiled: October 14, 2009Date of Patent: August 21, 2012Assignee: Dongguk University Industry-Academic Cooperation FoundationInventor: Keum-Cheol Hwang
