Dear Messaouda Ben Melouka

To determine if your current antenna is reconfigurable, you should check whether it can dynamically alter its fundamental properties like frequency, radiation pattern, polarization, or impedance. A reconfigurable antenna is designed to adapt to different operating conditions by changing these characteristics in real-time, often through components like PIN diodes, varactors, or MEMS switches integrated into the antenna structure.

If your antenna has elements that can be controlled electronically or mechanically to modify its behavior without physically replacing or adjusting the entire antenna, it's likely a reconfigurable one.
