Abstract:
1. A radiator structure having, when used operatively, a relatively stable impedance and radiation pattern over a wide bandwidth comprising: a planar radiator that has a outer edge; the outer edge having a pseudo-contact portion; wherein, when the planar radiator is positioned: the planar radiator is bilaterally asymmetric relative to the normal plane; and wherein, when the planar radiator is part of one of a monopole antenna and dipole antenna and being fed so as to transmit/receive an electromagnetic signal, the antenna: the planar radiator has an assessment width profile that extends from a member local maximum point to the pseudo-contact portion; wherein the assessment width profile has a profile local minimum point located between a first profile local maximum point and a second profile local maximum point; wherein the first profile local maximum point is located in a space extending from the profile local minimum point to and including the member local maximum point; wherein the second profile local maximum point is located in a space extending from the profile local minimum point to and including the pseudo-contact portion; wherein no other profile local maximum point is located between the profile local minimum point and either the first profile local maximum point or second profile local maximum point; wherein the profile local minimum point has a zero slope; wherein each of the first and second profile local maximum points has a zero slope; wherein the first profile local maximum point, wherein the second profile local maximum point, wherein the vertical distance between the profile local minimum point and the vertically nearer of the first and second profile local maximum points is at least 0.02λ wherein the horizontal distance between the profile local minimum point and the horizontally nearer of the first and second profile local maximum points is at least 0.01λ
