摘要：
This paper presents the design of 256 (16 x 16) Elements Planar Microstrip array antenna at K-band frequencies using corporate feeding network. The array antenna has been designed and developed for Miniaturized Satellite Communication (SATCOM) Ground Terminals. The Impedance bandwidth achieved for VSWR < 2.0 is 540 MHz (similar to 2.7%). The achieved Mid-band Gain of the array antenna Is about 29 dBi and E & H-Plane 3-dB beamwidths are 4.5 degrees each. The measured sidelobes level for the array is better than 12 dB. Overall efficiency of antenna array is about 50%. The array antenna wits developed using the MIC photolithography technique on the 30 mil (0,757 mm) RT - Duroid 5880 (epsilon(r) = 2.22) dielectric substrate.
