COMPACT superdirectivity ANTENNA HF bands with a cardioid polar pattern

摘要

1. Compact superdirectivity HF antenna with a cardioid radiation pattern, comprising: emitting vertical segments, the two-wire line, a low noise amplifier (generator) and a load with impedance consistent two-wire line, characterized in that due to the implementation superdirectivity and traveling-wave mode in the two-wire line is provided forming a cardioid directivity pattern with the effective radio equipment in accordance with chastot.2 wide range. Superdirectivity The compact antenna according to claim 1, characterized in that, to increase the effective height and emitter gain two-wire line has a compact form rhombic emitter to the load at the location of the plane of the rhombus vertically with respect to ground to include radiation mechanism (reception) apart vertical wires also all sides of the rhombus proportional current vectors projected on the vertical axis of the coordinate system.
