✦ Synopsis
Figure 5 Measured gain versus frequency width when compared with the bandwidth of other singlepoint feed single-layer CP antennas. In this design, the horizontal portion of the L-shaped probe forms a transmission line with the ground plane. Owing to the cancellation between the inductance existing on the vertical portion of the L-shaped probe and the capacitance introduced on the opencircuited transmission line from the horizontal portion of the L-shaped probe and the patch, the impedance bandwidth, axial-ratio bandwidth, and gain bandwidth can be enhanced. Furthermore, the use of the cross slot can effectively reduce the physical size of the circular patch.
