Multiband PIFA Antenna for Mobile Applications

The analytical analysis on PIFA technology is implemented. Various research works done on planar inverted-F antenna (PIFA) are classified and reviewed. Nowadays fast beyond growth of mobile technology. It's highly slammed on social life. The modern antenna designs needs a single element to be used in many band systems. This paper proposed many techniques based on multiband PIFA antenna for mobile communications. The PIFA antenna inserted of two assisted arms by connecting walls fed by 50 Ω patch element and a ground element. The patch element insert with slot and another arm to create and manage the various frequency bands. The proposed antennas various methodology such as L-slots E-slots, U-slots for achieved multiple frequency bands such as L-band 1GHz-2GHz(L), 2GHz-4 GHz(S), 4GHz-8GHz (C), 8GHz-12GHz(X) bands and higher bandwidth and gain by using shorting pin dielectric substrate, taper matching, dual feed, defected ground structures, etc. proposed band suitable for mobile and wireless communications, WLAN, WiFi, WiMAX, LTE, Bluetooth, radar communication, 4G and 5G communication etc. the design of antenna using FR4 lossy substrate material, coaxial probe feed line with 50 Ω impedance
