Patent number: 8970441Abstract: Provided is an antenna apparatus which employs a small number of antenna devices and is intended to obtain a desired pattern without adjusting amplitude level and phase of each antenna device. The antenna apparatus includes a first ridge horn antenna, and a second ridge horn antenna spaced apart from the first ridge horn antenna by a determined distance. Here, a multi-beam pattern is generated using a third-order mode beam pattern of a synthetic beam obtained by synthesizing beams respectively radiated from the first and second ridge horn antennas. Accordingly, the antenna apparatus can be simplified, and a desired multi-beam pattern can be obtained without adjusting signal level and phase of each antenna device. Also, by employing the ridge horn antennas as array devices, the antenna apparatus can be used in a wide frequency band.Type: GrantFiled: October 19, 2012Date of Patent: March 3, 2015Assignee: Electronics and Telecommunications Research InstituteInventors: So Hyeun Yun, Hong Yeol Lee, Chang Soo Kwak, Man Seok Uhm, Jang Sup Choi, In Bok Yom
