Multi-band antenna systems for communication systems are disclosed. An antenna system includes at least one low band dipole radiating element for radiating RF energy in a low frequency range and at least one group or column of high band dipole radiating assemblies for radiating RF energy in a high frequency range. The low band dipole radiating element may be constructed to provide improved control beam width stability of the high band dipole radiating assemblies and improved cross-polarization performance in the low frequency range. The high band dipole radiating assemblies include high band dipole radiating elements and shrouds surrounding the high band dipole radiating elements. The shrouds are configured to improve the beam width stability and cross-polarization of the high band dipole radiating elements, improve isolation between the high band dipole radiating elements and to shift resonance of the high band dipole radiating assemblies below the low frequency range.

Low band and high band dipole designs for triple band antenna systems and related methods

Unitary antenna dipole radiating elements are formed. Such elements include a base portion and a plurality of shaped arm portions unitarily formed on a side of the base portion. The antenna elements are configured to transmit and receive RF signals in a high frequency range.

Unitary antenna dipoles and related methods

Antenna array calibration systems and related methods include or utilize a plurality of signal splitter/combiner networks. Each of the signal splitter/combiner networks has a calibration signal sampling point in electrical communication with a signal input point, and signal output points. Each calibration signal sampling point may be capacitively coupled to a respective calibration source input of a calibration network. The signal splitter/combiner networks may be formed as phase-shifting networks.

Methods and systems for calibrating LTE antenna systems

Communications connectors communicatively and physically join a plurality of network elements. Communications connectors are substantially flangeless so as to provide a substantially continuous surface between the connector and network elements joined thereto. Communications connectors may include or be modified with a grounding surface or a seating member. Communications connectors include a variety of communicative contact surfaces and joining mechanisms, including those compatible with known 7/16 DIN connections. Methods include installing network elements to connection interfaces on connectors without the use of a flange or other exterior part. Methods optionally include applying an adhesive to connection interfaces to provide a breakable, locked connection between network elements and connectors.
