A multiple frequency directional antenna is provided. The antenna includes a radiating array aligned over a ground plane. The radiating array has at least two first elongated slots and two second elongated slots. The slots have different lengths to provide different operating frequencies. On the radiating array opposite the slots is a microstrip impedance matching and diplexing feed network. Radio frequency power is supplied to the antenna via the feed network.
