An eLORAN receiver may include an antenna and eLORAN receiver circuitry coupled to the antenna. The antenna may have a ferromagnetic core including a ferromagnetic medial portion and ferromagnetic arms extending outwardly from the ferromagnetic medial portion, a respective electrically conductive winding surrounding each of the ferromagnetic arms, and an electrically conductive patch element adjacent the ferromagnetic core.

An antenna assembly for a mobile communication device includes two antennas. The two antennas are disposed in a cavity defined in a side frame member of the mobile communication device. The two antennas are disposed adjacent with a gap in between. An antenna feed point is disposed in connection with each antenna. One antenna element of each antenna is disposed on a surface of side frame member surrounding the cavity.

A RFID tag for placement on a surface of a container that contains a liquid is provided. The RFID tag includes an IC chip configured to store identification information, a loop conductor connected to the IC chip, and an antenna unit that includes two conductor units connected to the loop conductor and extending away from each other from the loop conductor.

Systems and devices relating to antennas and antenna systems. A horizontal omnidirectional antenna has two dipoles with each dipole being in a V-configuration such that the arms of the dipole define an angle. The two dipoles are arranged so that the angles defined by each of the dipoles face and open toward each other. The horizontal omnidirectional antenna can be configured to operate with specific frequency bands. By nesting two instances of this antenna, with one configured for high band frequencies and one configured for low band frequencies, a dualband omnidirectional antenna can be obtained. The resulting antenna is physically compact and can be used in small MIMO systems along with vertical omnidirectional antennas.

A communication device includes an antenna system, a metal base, and a metal elevating pillar. The antenna system at least includes a dual-polarized antenna and a reflector. The reflector is configured to reflect radiation energy from the dual-polarized antenna. The metal elevating pillar is coupled between the antenna system and the metal base, and is configured to support the antenna system.

Methods and apparatuses are described for communicating primary signals over a high-speed primary channel, the primary signals having a beam pattern having a full lobe at a center of an axis of propagation and communicating auxiliary signals over a low-speed auxiliary channel, the auxiliary signals having a decoupled beam pattern having a null at the center of axis of propagation, the high-speed primary channel and low-speed auxiliary channel operating in full duplex.

A multi-band radiating array includes a reflector, a plurality of first radiating elements defining a first column on the reflector, a plurality of second radiating elements defining a second column on the reflector alongside the first column, and a plurality of third radiating elements defining a third column on the reflector between the first and second columns. The first radiating elements have a first operating frequency range, the second radiating elements have a second operating frequency range that is wider than the first operating frequency range, and the third radiating elements have a third operating frequency range that is lower than the second operating frequency range. Related radiating elements are also discussed.
