Antennenhet med en flerskiktstruktur

摘要

The present invention relates to an antenna unit (101) capable of operating in a satellite communication mode. The antenna unit (101) comprises interleaved circular patches for transmitting (102) and receiving (103) radio signals periodical arranged in a first and a second layer. The patches for transmitting (102) in the first layer are arranged in a first lattice (104) and the patches for receiving (103) in the second layer are arranged in a second lattice (105). The first lattice (104) is interleaved with the second lattice (105). Every other patch for transmitting (102) in the first layer has a corresponding patch for receiving (103) in the second layer, where each of the patches for receiving (103) are arranged in such a way that a center axis of the patches for receiving (103) coincide with a center axis of the corresponding patch for transmitting (102).
