<p>PROBLEM TO BE SOLVED: To provide a reference antenna of a broadband global satellite navigation system including a linear antenna array.SOLUTION: A linear antenna array includes a hollow support mast having a longitudinal axis, and a plurality of antenna element bays located along the support mast at regular intervals. Each antenna element bay includes a stripline excitation circuit board arranged perpendicularly to the longitudinal axis of the support mast, and a set of radiation elements arranged symmetrically around the support mast and connected electrically with the excitation circuit board. A suspended line circuit extends while penetrating the support mast, and electrically connected with the excitation circuit board of each antenna element bay, thus supplying an excitation signal to each radiation element.</p> |
