Patent abstract
With a differential feed line 103c, slot resonators 601, 603, 605, and 607 are allowed to operate in pair, a slot length of each resonator corresponding to a ½ effective wavelength during operation. Slot resonators which are excited out-of-phase with an equal amplitude are allowed to exist within the circuitry. Thus, positioning condition of selective radiation portions 601b, 601c, 603b, 603c, 605b, and 607b in the slot resonators is switched.
