An antenna arrangement for use in a cellular mobile radio system, consisting of four receiving antenna arrays grouped into two branches (2, 4). The first branch (2) consists of an antenna array (6) receiving vertically polarized signals, located adjacent an antenna array (8) receiving horizontally polarized signals. The second branch (4) consists of a similar arrangement (10, 12) spaced from the first branch to provide space diversity of the received signals. When a signal is received, the outputs from all four antenna arrays (6, 8, 10, 12) are fed to a combiner arrangement (14, 16, 18) to produce a space-diversity and polarization-diversity gain. |
