Abstract
A method to reduce the cost of a phased array antenna is employing subarrays composed of several element antennas and installing a phase shifter to each subarray not to each element antenna. In this case, it is important to suppress grating lobes because the periods of the subarrays are usually large compared with wave length. This paper proposes an aperiodic array antenna using diamond tiles as subarrays, which realizes both a low cost and low sidelobe characteristics.
