Abstract :
We presented two self-diplexing antennas. One is the self-diplexing antenna which consists of a patch as the upper antenna and a rectangular patch antenna with a hole as the bottom antenna and another one is the stacked self-diplexing antenna using a concave shaped patch and electromagnetic coupled patch. We simulated the S parameter characteristics and radiation pattern. Our proposed self-diplexing antenna structure suppress the mutual coupling between upper and bottom antenna by less than -25 dB using a patch with a hole and by less than -15dB using a concave shaped patch.
