27-3 反射板付き4Lポリループアンテナの指向特性-その2

抄録

This short paper says regarding radiation patterns of 4L-polyloop antennas with finite reflector, more precisely than previous thesis. We have obtained the most important result from the cascaded hexagonal antenna in the case of a λ/5 long common line between the adjacent loops. The half-power beam width of vertical radiation patterns is 39゜-50゜ throughout the band width which is 27% of it's centre frequency according to the measured data in this work.
