## A new and simple technique for obtaining circular polar-( ) ization CP radiation of a single-feed microstrip antenna is demonstrated. This CP design is achie¨ed by insetting a single slit to the boundary of the microstrip patch, and placing a single feed along an axis 45Рto the one containing

A circularly polarized antenna, realized in a low-cost technology with an integrated feed, is presented for the land-mobile satellite seruice. This antenna presents large bandwidth, high gain, and good axial ratio in all frequency ranges.
A no¨el compact circular polarization CP design of a single-feed equilateral-triangular microstrip antenna with a Y-shaped slot is presented. The Y-shaped slot is cut in the patch with its upper two arms facing either the triangle tip or the bottom side of the triangular patch. Results show that, wi
Figure 4 Signal gain and noise figure as a function of laser wavelength The effects of the laser wavelength on the probe signal at s 1550 nm are given in Figure 4. As mentioned earlier, s the presence of an oscillating laser signal within the wavelength range of 1528α1533 nm reduces the upper level
The design of a single-feed, reduced-size circularly polarized circular microstrip antenna with four slits equally spaced and inset at the boundary of the circular patch is experimentally in¨estigated. Results show that by increasing the slits' lengths to be about 0.8 times the disk radius, the circ
