  • 摘要:In this paper, we propose narrow element spacing arrays consisting of level sensitive phase multipliers (LSPM). A level sensitive phase multiplier comprises down converters, frequency multiplies with a phase locked loop (PLL), and an amplitude modulator. In order to confirm the capability of these arrays, we first examine the receiving patterns of two element arrays using the half wavelength dipoles and three element Yagi-Uda antennas. The number of the multiple function “ n ” is set to ”2” for measurement. The experimental results show that the quarter wavelength spacing arrays with LSPM have the equivalent receiving pattern of the half wavelength spacing arrays without LSPM. Second, the four element arrays using inverted-F antennas with LSPM, which have a 0.2 wavelength spacing, yield the equivalent pattern of a 0.8 wavelength spacing arrays without LSPM. In this case, the multiple function “ n ” is set to“ 4 ”.
