Abstract :
The dual-beam antenna concept is presented, along with theoretical and measured results. To meet the requirements given by the radar system, an array composed of 76 microstrip patches has been designed and fabricated at 5.29 GHz. It is a long rectangular array with elements arranged in two rows of 38 each. By using the conventional array theory, the far-field pattern cut along the long dimension of the array is calculated and presented. It is concluded that a relatively simple technique to generate two symmetrically squinted beams from a single array has been demonstrated.<>
