REVERSE L-SHAPED ANTENNA

PROBLEM TO BE SOLVED: To provide a reverse L-shaped antenna that can be constructed even in a three-dimensional structure or in a planar structure. SOLUTION: A reverse L-shaped antenna is configured by combining a ground plate and a reverse L-shaped radiation element to supply and receive transmission/reception power between the ground plate and the reverse L-shaped radiation element. Regarding the ground plate, the ratio of its area with respect to the reverse L-shaped radiation element has expansibility and regarding the reverse L-shaped radiation element, the ratio of its cubic volume with respect to the ground plate has expansibility. Since the ratio of the ground plate's area with respect to the reverse L-shaped radiation element has expansibility and the ratio of the reverse L-shaped radiation element's cubic volume with respect to the ground plate has expansibility, a desired radiation pattern can be obtained in accordance with expansion degrees of the ground plate and the reverse L-shaped radiation element.
