Wide-band slotted flower PIFA antenna for multimedia handhelds terminals

The rapid progress in wireless communication systems and handheld terminal devices has made the implementation of small multi-band antennas one of the main technical challenges. The number of wireless systems in which multimode mobile terminals are required to operate has been growing constantly in recent years. Nowadays handheld terminal phones use various cellular bands (GSM850/900/1800/1900 + 3G/4G/5G), wireless LAN, Bluetooth, Digital TV (DVB-H), FM radio, GPS, RFID, UWB, and WiMAX The narrow bandwidth constitutes the major disadvantage of microstrip antennas in most practical applications. This study proposes a new wideband small size flower-shaped PIFA antenna. The PIFA design has newest flower structure and is supported by two or three shorting pins. The layer patch is slotted by Allah name in Arabic. A capacitive feeding of the antenna was done via 50 Ω coaxial cable to achieve impedance matching. The simulation was done using the high frequency HFSS10 simulator for different scenarios. Simulated results on the return loss, the radiation pattern, and the gain are promising. The devised antenna could be implemented in many wireless communication standards such as PCS (1850-1990 MHz), UMTS (1920-2170 MHz), WLAN 802.11 b/g (2400-2484 MHz), WIMAX (2.5-2.69 GHz), and WIMAX (3.4-3.6 GHz).
