Aomway Cloverleaf


VNA measurements

RP-SMA version

Aomway cloverleaf, SMA and RP-SMA version. Both have very decent matching. The difference is most likely caused by the adapter and not by the antenna itself.

Same with hot glue + heat shrink

Regular cloverleaf vs. the same model covered in plastic (hot glue + heat shrink) to increase physical strength. It's clear that this modification hurts the performance of the antenna significantly.

The solid line is the correct polarization, the dashed line is the opposite polarization. Good radiation pattern, but axial ratio could be better.
