Microstrip Coupler with High Isolation
A method to improve the isolation of the microstrip coupler is presented. The pattern of the coupler is modified for phase velocity compensation which results in high isolation. Using this procedure, a 15 dB coupler is designed and fabricated at 0.9 GHz. A high isolation of 63.3 dB is measured. The validity of the design concept is verified by simulations and measurements.
متن کاملCEO power and earnings announcement tone with emphasis on the role of board oversight
The value of earnings reporting depends on the information it provides to the capital market. In the meantime, managers with the power and control of the situation interfere not only in quantity but also in the quality of reporting, so they declare profit in a more positive tone. However, supervisory management leads to protecting shareholder interests and reducing agency problems, limiting the...

متن کاملResonator with variable-reflectivity output coupler.
A novel resonator is proposed, in which the polarizing properties of standard grating and polarizing components (such as Brewster angle windows) inside the cavity are used to vary continuously the ouput coupling over a wide range of values. An analysis of the polarization properties of the modes of such a resonator is presented, and practical suggestions are made about the choice of the polariz...
