A printed compact antenna array for small wirelessly powered device operating at 900 MHz is proposed. The prototype is developed by printing antenna pattern on a 0.1-mm-thick flexible substrate and folding the printed sheet into a rectangular volume measuring 35 × 56 × 12 mm 3. The edge-to-edge distance between array elements is only 0.078 λ. An isolation structure is added to minimize the coupling between the elements. Measurement results show a -27-dB minimum coupling between the elements… CONTINUE READING
