Synchronized multiple-radio antenna systems and methods
Multi-radio antenna apparatuses and stations for wireless networks including multiple radios coupled to a single transmit/receive antenna, in which the antenna is highly synchronized by an external (e.g., GPS) signal. These multi-radio antenna systems may provide highly resilient links. Synchronization may allow these apparatuses to organically scale the transmission throughput while preventing data loss. The single transmit/receive antenna may have a single dish or a compound (e.g., a single pair of separate transmitting and receiving dishes) and connections for two or more radios.
TRANSMITTER
A controller of a transmitter outputs cyclically different digital data to equivalent transmission circuits, that is, RF circuits to generate a rotation polarized wave.

Dual-band antenna array with both fan beam and pencil beam
The present disclosure relates to a dual-band antenna array with fan beam and pencil beam. The antenna comprises a substrate and an antenna array arranged on the surface of the substrate, a first antenna element and a second antenna element are cascaded in an x-axis direction by a filter phase-shift line so as to form a subarray. A pair of T-shaped monopoles are symmetrically placed along the x axis at a certain distance above and below each of the first and second antenna elements, respectively, and a rectangular slot is embedded in the upper edge of the second antenna element to achieve good impedance matching. The second antenna element generates a fan beam at one frequency point or frequency band to have the performance of a wide beam, and generates a pencil beam at another frequency point or frequency band to have the performance of a narrow beam.

ANTENNA
An antenna for a mobile telecommunication base station has a plurality of radiating elements and at least two transmission paths or at least two receiving paths, which have different polarizations and are linked with two of the radiating elements and physically distanced from each other. The radiating elements are dielectric radiating elements. The individual radiating element interval between the radiating elements is less than 0.6, wherein is the wavelength of the center frequency of the lowest resonance frequency range of the radiating elements.
