One or more feedback elements generate a feedback signal in response to a transmitted signal outputted by each radiator of the antenna system. This feedback signal is received by each radiator, also described as a radiating element, and combined with any leakage signal present at the port of the antenna. Because the feedback signal and the leakage signal are set to the same frequency and are approximately 180 degrees out of phase, this signal summing operation serves to cancel both signals at the output port, thereby improving the port-to-port isolation characteristic of the antenna. Each feedback element can include a photo-etched planar metal strip supported by a planar dielectric card made from printed circuit board material. Such feedback elements can provide a high degree of repeatability and reliability in that the manufacturing of such feedback elements can be precisely controlled.

The invention provides a precision die forging and shaping technical method for automobile steering knuckle rough type parts. The precision die forging and shaping technical method mainly comprises the process steps of blanking, heating, extruding and drawing out a rod part, pre-forging, upsetting, performing material distribution and performing multi-way precision die forging and shaping and is specifically as follows: blanking through a cutting device, and heating to the temperature of 1080 DEG C-1180 DEG C in a medium-frequency induction furnace; placing a round bar which is well heated into a female die of an extruding and drawing-out die to form a stock comprising a cylindrical surface and a steering knuckle rough rod part; placing the stock after upsetting and material distribution into a multi-way die forging die, firstly enabling an upper male die and an upper die seat in the vertical direction to move downwards, and closing the upper male die and a lower female die for forging; and then using male dies on the symmetrical left side and right side in the horizontal direction to perform extrusion precision forging and shaping.
