Abstract: A radome has a base made of a light weight material having a dielectric constant of less than 2.0. A protective layer is secured to and at least partially covers an outer surface of the base. An antenna structure may be located inside of the radome to create a complete antenna. The light weight base material may be a solid having voids such as a solid foam and the protective layer may be a polyurea.

Abstract: An antenna includes a radiator and a feed stalk electrically coupled by first and second feed paths to the radiator. The feed stalk includes a common-mode rejection filter, which has first and second ports electrically connected to the first and second feed paths, a first inductor electrically coupled to the first port and a second inductor electrically coupled to the second port. The common-mode rejection filter is configured so that a first impedance electrically coupled to the first port is equivalent to Z 1, and a second impedance electrically coupled to the second port is equivalent to Z 2 , where: Z 1 = R 1 + jωL 1 + jωM(I 2 /I 1 ); Z 2 = R 2 + jωL 2 + jωM(I 1 /I 2 ); M ≈ L 1 ≈ L 2 ; R 1 and R 2 are the resistances of the first and second inductors; L 1 and L 2 are the inductances of the first and second inductors; M is a mutual inductance between the first and second inductors; I 1 and I 2 are the first and second currents into the first and second ports; and ω is the angular frequency of the first and second currents.

Abstract: Base station antennas are provided herein. A base station antenna includes a multiband beam-former array having a plurality of vertical columns of radiating elements. In some embodiments, at least two of the vertical columns are commonly fed for a first frequency band of the multiband beam-former array that is lower than a second frequency band of the multiband beam-former array. Related methods of operation are also provided.
