An antenna includes a ground plane, a dielectric, and an active radiating element. The dielectric is disposed on the ground plane, and the active radiating element is embedded in the dielectric for transmitting and/or receiving an RF signal. The antenna also includes a feeding element and a ...
H-plane half-power beamwidth determines the beamwidth of an antenna in the horizontal plane. When beamwidth is wide, good signal coverage is available at the sector boundary. However, when the downtilt angle becomes larger, beam distortion is more likely to occur, leading to overshoot coverage. ...

Systems and methods for reducing the beamwidth of an antenna system are provided. An evanescent field generator generates an evanescent field representing a far field radio frequency (RF) signal received at the antenna system. A negative refractive index lens assembly focuses the evanescent field onto...

The meaning of BEAMWIDTH is the angular diameter of the region adjoining an antenna through which the reception of the signal is best.
An antenna assembly for radio frequency energy is disclosed wherein individual antenna elements making up an array are fed in an improved manner so that the width of a directive beam, or beams, formed by such elements is, or are, maintained substantially constant over a wide band of operating...
