Provided is an antenna device for position detection that can determine the current position, using a GPS receiver with a simple structure, with high accuracy comparable to that of an expensive positioning device, and also provided are a position detection device provided with the antenna device and a position detection method. The current position is determined using a GPS that receives signals from satellites orbiting around the earth and determines the current position. Data communication is performed with an antenna main body including: an antenna member provided, at an end thereof, with a receiving section for receiving signals from the orbiting satellites; and a rotation mechanism for rotating the antenna member circularly in the horizontal direction at a substantially uniform speed. The current position is determined based on the signals from the orbiting satellites that have been received by the receiving section.
