Study of electromagnetic coupled microstrip patch array antenna for bandwidth enhancement
Dr. RK Verma
In this communication a sixteen elements microstrip array antenna of rectangular patches is presented which is feed by source of 10 GHz with electromagnetic coupled feeding technique for the study of enhancement of Bandwidth. The patches are printed on the RT‐duroid substrate. The radiation patterns for E‐plane, H‐plane and array geometry has been plotted and presented here. The radiation parameters of this array antenna are also compared with the same array antenna configuration without using electromagnet coupled technique. Comparison shows that the electromagnetic coupling has provided around 41% enhancement in bandwidth compare to simple patch antenna.
