ABSTRACT:
A wideband antenna in which a first and second conductive element are arranged so that a notch is formed between the first and second conductive element, wherein the first and second conductive element have shapes satisfying two conditions (i) a sum of the lengths of sides facing the notch and a first side terminating at one edge of a wider opening of the notch, these sides pertaining to the first conductive element, and the lengths of sides facing the notch and a second side terminating at one edge of the wider opening, these sides pertaining to the second conductive element, is approximately half of a first wavelength, and (ii) a sum of the lengths of sides pertaining to the first conductive element and facing the notch, and the lengths of sides pertaining to the second conductive element and facing the notch is approximately half of a second wavelength.
