Abstract

The invention relates to a base station of a communication network which comprises a casing, a transmitting and receiving device housed in the casing, and an antenna connected to the transmitting and receiving device. The antenna is formed as a patch antenna which comprises at least one receiving antenna patch and at least one transmitting antenna patch spatially separated from the receiving antenna patch. The receiving and transmitting antenna patches are preferably attached to the outside of the casing of the base station. Two or more separate receiving antenna patches may be connected to a common receiving feed line for connection to a receiving circuit of the base station. Likewise, two or more separate transmitting antenna patches may be connected to a common transmitting feed line for connection to a transmission circuit of the base station.
