Abstract :
A dual series-fed, four microstrip patch array antenna that utilizes planar design for ease of fabrication and signal routing is presented. The natural tendency of a series fed array to have beam tilting over frequency is circumvented by using opposing, anti-symmetric balanced feed points. This approach makes this element suitable for low cost frequency-hopped phased array antennas. An approach for inter-element matching to evenly distribute power to each element is also described. The antenna operates at 4.85 GHz with approximately 600 MHz of bandwidth.
