A dual-band antenna array (50) for use in a base station for mobile telephone communications consists of a first linear array of microstrip or patch antennas (52) for use over the GSM band and a second linear array of crossed dipoles (56) for use over the PCN band. The PCN antennas are at half the spacings of the GSM antennas. Alternate ones of the PCN crossed dipole antennas are located above respective GSM patch antennas, and a conductive plate or sheet (66) between them functions both as a parasitic element for the microstrip antenna and as a reflector for the crossed dipole antenna.
