Open-loop GPS antenna

摘要

An open-loop GPS antenna configured on an insulation object is provided. The open-loop GPS antenna includes a feed, a high frequency circuit, a low frequency circuit and a ground. The high frequency circuit includes a first end, connected to the feed, and a second end. The low frequency circuit includes a third end and a fourth end. The third end is disposed parallel to the second end so as to couple to the second end and generate a capacitance effect to transmit a signal. The fourth end is connected to the ground.
