Antenna array with low Rx and Tx sidelobe levels
Abstract
The various technologies presented herein relate to mitigating or reducing sidelobe levels during operation of an antenna array. Power coefficients operating across an antenna array are tapered to facilitate a power concentration at central region of the antenna array while power coefficients of a lower magnitude are generated at the periphery of the antenna array. Power coefficient variation can be effected by at least one of electrical path length, number of antennas being powered in a particular antenna subarray, a number of T-splitters incorporated into an electrical path servicing an antenna, etc. Electrical coupling of a pre-T/R stripline and a post-T/R stripline can be achieved in conjunction with operation with a dielectric layer, wherein the dielectric layer acts as a dielectric at the K.sub.u frequency band. Further, phase delay can be applied to at least one electrical signal to facilitate concurrent delivery of power across the antenna array.
