A new planar triple band microstrip-fed Planar Inverted-F Antenna (PIFA) for the use in GSM835 band (698–989 MHz), DCS1940 band (1824–2033 MHz) and Wi-Fi2340 band (2302–2548 MHz) is reported. A numerical study based on the parameters like ground plane length, height of radiating plate, feeding point position, shorting plate width, and position, was...

... structure is formed from the integration of the two short-circuited resonant elements [2,13]. Figure 3 shows the measured experimental results and simulated S11 parameters (reflection coefficient) of the constructed prototype. Good agreement between the measured data and the simulated results was obtained. ...

This research work presents a low profile slotted planar invertedF antenna (PIFA) on a reactive impedance surface (RIS) for multiband. The quad-band frequency antenna for 2.4 GHz (WLAN), 4.2 GHz (C-band satellite downlink), 7.1 GHz (C-band satellite uplink), and 9 GHz (X-band )for wireless applications. The structure of the proposed PIFA has a compacted patch size of 23.33 mm × 2.66 mm × 1 mm placed on a dielectric substrate flame retardant 4(FR4) material, along with tangent loss = 0.02. The proposed antenna used two dielectric substrates whose heights are h1 = 1.59 mm and h2 = 1 mm . The rectangular slot is added in a radiating patch of the PIFA for multiband operations. The proposed antenna improves the parameters such as reduction scale, efficiency, narrow bandwidth, and gain enhancement. The slotted PIFA shows a quad-band with an S11 <-10 dB bandwidth of approximately 15.83% (2.24-2.62 GHz), 11.19% (3.93-4.4GHz), 12.67% (6.90-7.80GHz) and 10.55% (8.29-9.24GHz) under measurement. The proposed antenna design is excited by 50Ω microstrip line feed. The antenna exhibits radiation pattern, gain, and impedance matching across their operating bandwidths to demonstrate the benefits of multiple PIFA.
