✦ Synopsis

Figure 8 S PS1 and PS2 curves and differential phase shift behavior DIFF curve for a phase shifter with N s 4, Z s 100 ⍀, 21 c u s 33 ⍀, ⌬ s 90Њ tot problem of implementing impractical values for the susceptance ratio Rb therefore can be overcome by utilizing a larger number of cascaded cells.

CONCLUSION

A traveling-wave digital phase shifter has been proposed. A circuital approach, based on the image parameter representation of two-port networks, has been utilized to derive an analytic model for the distributed structure. Closed-form expressions have been obtained for the characterization of the component. A design methodology has been presented, optimizing the electrical performance and also obtaining an appreciable size reduction. Moreover, no lumped-element approximations have been performed for the modeling of the transmission-line sections.

A circularly polarized CP circular patch microstrip antenna with a cross slot using an L-shaped probe fed by a microstrip line is designed and measured. With the single L-probe, the impedance bandwidth, the axial-ratio bandwidth, and the gain bandwidth are 27, ( ) 3.47, and 26%, respecti¨ely, for th
