A slot-excited corner reflector for use in Band V (610-960 Mc/s)

The directional aerial described employs a corner reflector excited by a four-tier slotted cylinder. It was used during a series of test transmissions in Band V (610¿960 Mc/s) which required an aerial capable of withstanding severe climatic conditions for long periods without attention. A design suitable for operation at 900Mc/s is described; the measured results include admittance characteristics and radiation patterns in the horizontal and principal vertical planes.
