Abstract A PIFA in one embodiment includes a radiating member including a feed point, a shorting point, a first radiating element having a starting point and a terminating point coiled as a longer path terminated at an outer edge of a ground plane and being open for generating a resonance mode having a low frequency, and a second radiating element having a starting point connected to the starting point of the first radiating element, and a terminating point extended to form a shorter path terminated at the outer edge of the ground plane, the terminating points of the first and second radiating elements adjacent for generating a resonance mode having a high frequency; low and high frequency medium frequency regulators for adjusting resonance frequencies of two different resonance modes a substrate; a feed member; and a shorting member.
