A compact-range wireless access system in the 60 GHz-band has been proposed for multi-Gb/s data transfer. A prototype Gigabit Access Transponder Equipment (GATE) was made to evaluate the system performance of bit-error rate (BER) and signal-to-noise ratio (SNR). An error-free communication zone up to 11 m is available by adopting the 32×32 and 64×64-element waveguide slot arrays in the transmitter. However, the BER degrades especially for the propagation distance less than 1 m. In this study, the concept of intersymbol interference is introduced in the antenna field for the first time. An equivalent baseband communication system is newly proposed to evaluate the wireless channel including antennas. The analysis procedure and equations are provided for the calculation of ISI. The ISI as well as BER for the circular aperture antenna is theoretically analyzed as a function of propagation distance first. The ISI for the fabricated 64×64-element array is evaluated as well by measuring the transfer functions of the wireless channel directly. |
