teaching of the prior art the 39 897 patent teaches a currently well known design paradigm of using u201c closely spaced conductors u201d for feed lines and feed conductors in an attempt to neutralize radiation from them the invention antenna maintains a substantial separation of those conductors to improve overall performance in combination with using high impedance spaced apart feed lines and feed conductors separation distance 141 of feed lines and feed conductors results in increasing the effective radiating surface of the antennas of the invention thereby reducing overall size thereof over the prior art antennas a further advantage of the in invention antenna as shown in fig7 is use of a high q air capacitor in the antenna loop resulting in uniform current distribution across the radiator surfaces arranging feed points 133 as in fig6 to be separated from each other at one quarter wavelength apart effectively reduces the resonant frequency of the antenna this in turn results in significant size reduction of the overall antenna as to a peripheral size the 39 897 patent teaches that each feed line should be connected to a two dimensional radiator at it 39 s end point and that each feed line should be connected to one or two radiators which share no connection with radiators of the other feed line in the present invention two back to back concave and symmetrical three dimensional radiators are fed with inputs from both feed lines at a mid point of a height of the antenna with such dual feeds to a.
