Differential fed slot antenna

摘要

By differential supply of electricity railroad track 103c, in order for slot length when operating to become 1/2 effective wavelength, the slot resonator 601 which is set, 603, 605 and 607 opposite it operates, it appears the slot resonator group which such as opposite phase with amplitude is driven inside the circuit, changes the arrangement condition of selective emission region 601b inside each slot resonator, 601c, 603b, 603c, 605b and 607b.
