Abstract
Work is reported on the development of a new wide band H-plane sectoral horn antenna which is not subject to the usual l/f variation of beamwidth with frequency. The upper frequency limit of wide band horn operation is dictated by the onset of TE30 mode in the horn feeder and throat. A compensating moding device in the feeder is optimised so that operation over greater than 3:1 bandwidths can be obtained.
