Research of a flat in phase two-dimensional-periodic overrange antenna array of flared notch hornes

Using numerical modeling, a study was carried out of the matching and radiation characteristics of a flat in-phase two-dimensional - periodic over-band antenna array of flared-notch horns depending on the period and length of the array elements, input and output impedance, type of feed lines and screen shape. A 64-way power divider with outputs in the form of symmetrical two- strip lines has been developed and studied, and an 8 × 8 array of elements with a power divider as a power feed system has been studied. It is shown that the array with the U-shaped screen provides an operating frequency bandwidth of more than 20:1.
