A Multi-Beam Array Antenna Employing Simple 4 × 2 Beam-Forming Network Integrating Magic-T and Hybrid Coupler
This paper presents a multi-beam array antenna using a simple 4×2 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° and + 18°) are experimentally verified using a 5.8-GHz prototype.
