Abstract

A modified E-shape microstrip patch antenna with wide-bandwidth is employed in a 1×4 linear array. The array antenna shows a 42.1% fractional bandwidth using S₁₁ criteria of ≤ -10dB. The array antenna was fabricated with 0° progressive phase shift and experimentally verified with the help of a prefabricated 1:4 Wilkinson equal power divider for impedance matching and radiation patterns. The beam steering performance of the array antenna is also explored for different progressive phase shifts.
