Abstract :
The work presents a new dual-polarized microstrip patch antenna fed by double slot-coupled feeds of 180° phase shift and a coplanar microstrip feed. The simulated and measured results show that this antenna achieves a high isolation (<-41 dB) across the entire operating frequency and low cross-polarization level (<-30 dB).
