Abstract: The article presents the design of a linearly polarized non-radiating edge directly coupled microstrip array antenna for X-band applications. The array elements are excited by corporate feed network, which enhances the impedance bandwidth of the two element non-radiating edge directly coupled rectangular microstrip array antenna (TNDRMAA) by 30.12%. The measured results for array antennas in term of reflection coefficient, radiation pattern, half power beam width (HPBW) and gain are presented.
