A miniaturized ultra wideband (UWB) planar array antennas for C-band aircraft weather RADAR applications is presented. Firstly, the effect of the ground plane is studied. Later, the realization and experimental validation of the geometry that has an UWB characteristic are discussed. This array antennas is composed of a twenty-four radiating element that is etched onto FR-4 substrate with an overall size of mm3 and a dielectric constant of . The results show that this miniaturized array antennas gives us a bandwidth which is about and a gain greater than 13 dB which are required in aircraft weather radar applications.
