Abstract: A tunable antenna including a first radiation element, a shorting element, a feeding element, and an impedance matching circuit is provided. The first radiation element provides a first resonant path, so that the tunable antenna covers a first band. The first band includes a plurality of sub-bands. The shorting element is electrically connected to the first radiation element and has a ground point. The feeding element is electrically connected to the first radiation element and has a feeding point. The impedance matching circuit is electrically connected to the shorting element and adjusts impedance of the tunable antenna according to a control signal, so that the tunable antenna is switched between the sub-bands.

Abstract: 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.
