Abstract

Apparatuses, systems, and methods for a folded dipole antenna are provided. A folded dipole antenna may include a radiating element with a first side and a second side and a RF feed. The first side of the radiating element may include a first portion, a second portion, and a first fold between this first portion and this second portion. The second side of the radiating element may include a first portion, a second portion, and a second fold between this first portion and this second portion. The first portion of the first side and the first portion of the second side have a first diameter that is different from the second portion of the first side and the second portion of the second side have a second diameter. The folded dipole antenna may also include one or more tuning bars.
