  The four arm spiral antenna consists of four specially curved metal lines. No grounding is required. It has the characteristics of Zapper antenna and vertical antenna. With this ingenious structure, the antenna has a 3dB gain in any direction, increasing the time for satellite signal reception. The four arm spiral antenna has a 360 degree reception capability. Therefore, when combined with the pda, the four arm spiral antenna can receive regardless of the placement position of the PDA, which is different from the limitation that the flat GPS antenna needs to be placed horizontally for better reception. With this antenna, when the satellite appears at 10 degrees above the ground level, the signal transmitted by the satellite can be received.

  However, if there are many interference sources near the ground receiving station, the four arm spiral antenna is not applicable, because the four arm spiral antenna has horizontal gain, which will amplify the noise together and interfere with the reception of satellite signals. However, with the progress of science and technology, the four arm spiral antenna produced now can break through the limitations of many traditional antennas. The antenna is made of ceramics. The Near Field is very small, only about 3~5mm, while some traditional antennas have a Near Field as high as 1m. The smaller the Near Field, the less interference the human body will cause when the user holds the GPS device. The characteristics of the current four arm spiral antenna also include the complete Balun circuit design, which can isolate the noise around the antenna, thus allowing antennas with various functions to coexist in a small space without mutual interference. The importance of this feature is self-evident for handheld electronic products with increasingly diversified integration functions and emphasis on thinness and smallness.
