Design of a Miniaturized Butler Matrix in IPD Process for 60 GHz Switched-Beam Antenna Arrays
Résumé
In this paper, we present the design and realization of a miniaturized Butler matrix for 60 GHz applications. The matrix is realized using the IPD process from ST Microelectronics, Tours. Using new miniaturized branchline couplers and the IPD process, the Butler size is reduced by 90%. Simulation results show an insertion loss of 2.25 ± 0.95 dB and a maximum phase error of 10° in the whole 57-66 GHz band.
