A radar antenna suitable for a drone is provided, which is able to compensate for the agility of drone motion. The radar antenna contains a sandwich of two printed circuit boards between three conductive plates. A first printed circuit board comprises a preferably circular array of first antenna elements such as dipoles. A second printed circuit board, parallel to the first printed circuit board, comprises an array of second antenna elements. One of the array of first antenna elements and the array of second antenna elements is an array of transmission antenna elements and the other an array of reception antenna elements. The first printed circuit board is located below the second printed circuit board. Three conductive plates are used to shape the antenna patterns from the antenna elements so that the main lobes of the antenna patterns are directed obliquely downwards and the antenna patterns from the different array at least partly overlap, suppressing vertical side lobes. A first conductive plate separates the first and second printed circuit boards. A second conductive plate is located above the second printed circuit board, extending radially outward beyond the first conductive plate. A third conductive plate is located below the first printed circuit board. The first conductive plate extends radially outward beyond the third conductive plate.
