Gain enhancement and size reduction for LPDA antennas

摘要

The present invention is a size reduction and improved gain El pidieyi (LPDA) as for the antenna, and more particularly by applying the meander techniques sikyeotgo size reduction to about 25% compared to conventional EL pidieyi (LPDA) antenna, and the active regions to meet the same bandwidth as the existing El pidieyi (LPDA) antenna, at least a reduction in the gain proposed a method to widen, which further by applying the branch line for each single element of that size reduction and improve performance by increasing the gain-bandwidth-enhanced El pidieyi (LPDA) relates to an antenna. The invention uses a technique for improving the small by using a (dipole length by 30% reduction) of broadband single element holding the frequency bandwidth of the existing El pidieyi (LPDA) antenna gain and widen the active region (gain), the broadband Once this time is shaped single element ( ) and being configured. ;
