摘要：

This paper presents a multi-beam array antenna using a simple 4x2 beam-forming network (BFN). The BFN consists of a magic-T, hybrid coupler, and two single-pole double-throw (SPDT) switches. Simulated results confirm the BFN concept with good impedance matching and high port isolation. When an antenna array is connected with the proposed BFN, four beam patterns can be obtained. The multi-beam radiation patterns (sum, difference, and two tilted beams at -15 degrees and + 18 degrees) are experimentally verified using a 5.8-GHz prototype.
