ABSTRACT:
A thin planar curved microstrip antenna is described which exhibits substantially constant input impedance characteristics over a wide frequency band. The impedance characteristic is achieved by shaping the ground surface such that the ratio of the width of the radiating element to its distance from the ground surface stays constant for a given curvature.
