MICRO-MINIATURE BASE STATION ANTENNA

摘要

The purpose of the present invention is to provide a small base station antenna having characteristics such as a wide bandwidth, a high gain and improved isolation. The small base station antenna according to an embodiment of the present invention comprises: a substrate provided inside a cube to have a first and a second microstrip line etched; a first inverted F antenna including a first metal short-circuit plate provided on the first microstrip line and a first radiation patch provided on the first metal short-circuit plate; a second inverted F antenna including a second metal short-circuit plate provided on the second microstrip line and a second radiation patch provided on the second metal short-circuit plate to face the first inverted F antenna; and an isolating body provided between the first inverted F antenna and the second inverted F antenna. According to the present invention, a wide bandwidth and a high gain can be obtained and isolation between the antennas can be improved.
