Abstract
The present disclosure relates to a dual-band antenna array with fan beam and pencil beam. The antenna comprises a substrate and an antenna array arranged on the surface of the substrate, a first antenna element and a second antenna element are cascaded in an x-axis direction by a filter phase-shift line so as to form a subarray. A pair of T-shaped monopoles are symmetrically placed along the x axis at a certain distance above and below each of the first and second antenna elements, respectively, and a rectangular slot is embedded in the upper edge of the second antenna element to achieve good impedance matching. The second antenna element generates a fan beam at one frequency point or frequency band to have the performance of a wide beam, and generates a pencil beam at another frequency point or frequency band to have the performance of a narrow beam.
