Abstract
An antenna unit with anti-feed power divider function includes a first substrate, a second substrate, a microstrip antenna layer, a grounding layer, a microstrip wire layer and two vias. The microstrip antenna layer is disposed on an upper surface of the first substrate and has plural microstrip antennas and a high impedance wire connected to the microstrip antennas. The grounding layer is set on a lower surface of the second substrate. The two vias penetrates the first and the second substrates to electrically connect the microstrip wire layer and the microstrip antennas, wherein the two vias have different sizes. An antenna module thereof is also disclosed. The present invention precisely controls the power ratio and phase difference, utilizable for generating a symmetric and asymmetric feeding antenna array, thereby achieving a hierarchical feeding and minimizing the antenna structure.
