A parasitically-coupled dual-band patch antenna is described. The antenna includes an inner conductor having one or more feed holes. The antenna also includes an outer conductor surrounding the inner conductor in a radial direction. The antenna further includes one or more feeds each having a vertical portion that passes through the feed holes and a horizontal portion that extends in an outward direction from the feed holes toward the outer conductor. The feeds are conductively connected to the outer conductor. The horizontal portion of each of the feeds is separated from and is conductively disconnected from a top surface of the inner conductor.

An information handling system (IHS) includes an antenna system. The antenna system includes an antenna; a radiating element, the radiating element being capacitively coupled with the antenna; and, a tuner module electrically coupled to the antenna and the radiating element, the tuner module tuning the antenna and the radiating element.

Disclosed is an antenna that enables dense packing of low band, mid band, and C-band radiators. The low band radiators have a plurality of dipole arms that minimize re-radiation of either RF energy emitted by either the mid band or C-Band radiators. In one embodiment, the dipole arms are formed of a two-dimensional structure that has a shape that substantially prevents re-radiation in both the mid band and the C-band. In another embodiment, the dipole arms have two different configurations: a first configuration optimized for preventing re-radiation in the mid band, and a second configuration optimized for preventing re-radiation in the C-Band. In the latter embodiment, the low band radiators in close proximity to the mid band radiators have dipole arms of the first configuration, and the low band radiators in close proximity to the C-Band radiators have dipole arms of the second configuration.

A mobile terminal and an antenna that includes a feeder and a radiating element. The radiating element includes a first radiating patch and a second radiating patch. The first radiating patch and the second radiating patch are located on one side of the feeder and form a loop together with the feeder. An adjustable component configured to control the feeder and the second radiating patch is disposed on the feeder between the first radiating patch and the second radiating patch. The first radiating patch has a first extension part extending to an opposing side of the feeder.

A multiband digital data network infrastructure comprises a network of access points (APs). Each AP includes a differential segmented aperture (DSA) comprising a two-dimensional array of electrically conductive tapered projections disposed on a support board, modular analog front ends (MAFE's) configuring the DSA for different respective wireless services, an in phase/quadrature (IQ) board, and one or more network cards. The network of APs support two or more different wireless communication protocols operating in different RF bands. In some embodiments, each AP of the network supports both a cellular service and a WiFi service using the same DSA. In some embodiments, the network of APs form a network of cell towers of a cellular service. In some embodiments, the network of APs form a network of APs of an indoor wireless network.
