Patent abstract
Opposite ends open slot resonators (601, 605) having a slot length during an operation set to become one half of effective wavelength are operated by a differential feeder liner (103c) and a slot resonator group excited with a reverse phase/equal amplitude is made to emerge in the circuit, and arrangement conditions of the open end points of selective radiation parts (601b, 601c, 603b, 603c, 605b, 605c, 607b, 607c) in each slot structure are switched dynamically.
