TRIPLATE DIPOLE ANTENNA ARRAY WITH C SHAPED GROUND PLANE

摘要

The present disclosure relates to a high gain radiating element and a linear array for a mechanically rotating antenna used in portable radars having very high rpm. An 18 element linear array, having high gain triplate dipole with ‘C’ shaped ground plane as radiating element is described. The linear array is fed by air dielectric stripline feed network to achieve low side lobes. The vertical height of the invented antenna array is reduced by the use of C-shaped ground plane to keep linear arrays very close to each other in planar array configuration. The antenna arrays has larger air gap between linear arrays allowing air to pass through it in planar array configuration which enhances wind load withstanding capability of antenna required to be rotated at high speed in high wind environment.
