摘要: The invention relates to a beamforming antenna system (100). The beamforming antenna system (100) comprises a cylindrical beamforming antenna (101) having a cylindrical surface and an array (102) of antenna elements. The beamforming antenna system (100) further comprises a driving circuit (103) being configured to drive a subarray of the array (102) of antenna elements to generate a spatially directed transmission beam. The driving circuit (103) comprises a storage (105) being configured to store reference phase shift values for generating spatially directed transmission beams using a planar beamforming antenna. The driving circuit (103) further comprises a processor (107) being configured to select a subset of the pre-stored reference phase shift values, to adapt the selected subset of pre-stored reference phase shift values to the cylindrical distribution of the array (102) of antenna elements of the cylindrical beamforming antenna (101) to obtain adapted phase shift values, and to drive the subarray of the array (102) of antenna elements of the cylindrical beamforming antenna (101) using the adapted phase shift values to generate the spatially directed transmission beam.

摘要: A signal combiner for combining transmission signals to be supplied to four antennas devices, wherein two of the antenna devices are polarized in a first orientation and two of the antenna devices are polarized in a second orientation essentially orthogonal to the first orientation. The signal combiner comprises: four input connections arranged to receive the transmission signals; four output connections arranged to drive a respective one of the four of antenna devices using respective output signals. The signal combiner is arranged to combine transmission signals supplied on each input connection to all of the four output connections using beam forming and phase adjustment, such that, in use, each supplied transmission signal generates a central beam polarized in the first orientation and a side beam polarized in the second orientation. It is also presented a corresponding method, computer program and computer program product.
