A novel planar inverted-F antenna for 2G/3G/LTE systems

In this paper, a novel planar inverted-F antenna (PIFA) operating at six bands (GSM850, GSM900, DCS1800, PCS1900, UMTS2100, LTE2300) is proposed. By adding a parasitic element and two slots in the patch of basic PIFA, the bandwidth on the upper frequency band can be improved to cover more communication systems. All the simulated and measured results show that the proposed PIFA possesses −6dB bandwidth 185 MHz (805 MHz to 990 MHz) at the lower frequency band and 815 MHz (1705 MHz to 2520 MHz) at the upper frequency band. Moreover, the proposed antenna exhibits good performance of total radiated power (TRP), (18 ∼28 dBm) and total isotropic sensitivity (TIS), (−91 ∼−107 dBm), under the free space environment. Thus, the novel PIFA is suitable for 2G/3G/LTE mobile communication systems.
