Compact cloaked dipoles with wideband operation for multiband antennas

Abstract

Methods and apparatus for use as an antenna assembly are disclosed. In one embodiment, the antenna assembly includes a base portion functioning as an interface between the antenna assembly and a reflector; a base portion to radiator feed structure; and a radiator. The radiator includes: a plurality of resonator arms, each of the resonator arms including a plurality of inductive capacitive filters, the plurality of inductive capacitive filters including a straight-line portion and a meandering portion that act as an inductive portion of the inductive capacitive filter. A gap in the meandering portion acts as a capacitive portion of the inductive capacitive filter. Multiband antenna assemblies that utilize the aforementioned antenna assembly as well as methods of their manufacture and use are also disclosed.

Dependencies are inferred from the claim text.
