Ku-band dual-polarized patch antenna array arrangement using patch sharing technique

Patch sharing technique, to the best of the authors´ knowledge, is the first time proposed in the application of patch antenna array arrangement. With this approach, the distance between antenna unit cell can be decreased significantly, which the inter-element distance is assumed as a key parameter for beam forming and to control sidelobe level of antenna array. However, most of the time this distance is difficult to decrease due to the profile of antenna unit cell and taking into account of electromagnetic coupling between each unit. In this article, the authors would like to introduce two antenna arrays which are arranged in 1D and 2D separately with the proposed approach, simulated and measured results indicate that patch sharing technique works well.
