Abstract :
An 8 × 4 microstrip antenna array operating within 24 GHz frequency range has been shown. The presented antenna features two beams: a broadside beam and a dual beam. It allows for detection of targets in two different ranges and at two different angular positions. Additionally, the antenna can be used for the direction finding. The proposed antenna array uses `through-element´ series feeding technique for dissipation losses reduction as well as the stacked laminate structure to separate the radiating elements and the feeding network, which allows for achieving satisfactory radiation patterns in a wide frequency range.
