Abstract
There is provided a low-cost wide band antenna having an ultra-wide band and high performance. The wide band antenna includes an antenna element to form a shape of a ridge waveguide open cross-section structure together with GND (10) when it is spread. The antenna element has a ridge element portion (13) corresponding to the ridge portion of the ridge waveguide and a radiation element portion (14) corresponding to the wall of the ridge waveguide and extending from the ridge element portion (13) for electromagnetic wave radiation. Moreover, the antenna element has an opposing auxiliary element (12) having the same shape and structure as the ridge element portion (13). The radiation element portion (14) has an end arranged on the GND (10). The ridge element portion (13) has a tip end connected to a power supply terminal (100).
