Abstract
Low passive intermodulation (PIM) antenna assemblies and methods for utilizing the same. In one embodiment, the low PIM antenna assembly includes an ultra-wide band quarter wave monopole over ground plane antenna apparatus that operates within a band from 698-5900 MHz. The radiating element is comprised of three (3) features that are separated from one another by one hundred twenty (120°) thus producing a triangular shaped pattern. Such a configuration reduces the nulls by about twenty percent (20%) as compared with similar antenna implementations having flat radiating elements. Moreover, in order to reduce the diameter of the ground plane while simultaneously increasing the electrical length of the ground plane, forming of the ground plane is required. Methods of using the aforementioned low PIM antenna assembly are also disclosed.
