Circular Patch Antenna

[Admin 2545]

The schematic diagram of the antenna is shown in Figure 1. Two or one sectoral slots are made on the patch surface. The presence of the sectoral slots on the patch causes the antenna to resonate at two adjacent frequencies, which results in the enhancement of the impedance bandwidth

diameter : 62 mm
mouth pacman : 5 mm
spacer reflektor to patch : 8 mm
