Abstract: Miniaturized multi functional planner array antennas are presented for both L and S bands in this paper. A 3×8 array is proposed and the distance between antenna elements is only λ/2 so that size reduced significantly. The two dielectric substrates FR4 and RT duriod 6010 are used for different antennas. The antenna with FR4 substrate is fabricated and compared the results with simulated values. Coaxial feeding technique is adopted. Dual frequency multi functional array is simulated .Better gains, return losses and radiation patterns are obtained .The circular polarization is obtained by truncating the elements and it is useful for navigation. The results are compared with existing multi object tracking radar (MOTR).
Keywords: Multi Frequency, Array, Coaxial feed, MOTR, Circular Polarization.
