Compact triple‐band PIFA with high bandwidth and gain for multiple mobile services

Abstract

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 done to obtain an optimized antenna. The simulation allowed the characterization of the designed antenna as a function of different antenna parameters like S11, resonant frequency, bandwidth, gain, radiation pattern, and electric and magnetic fields distribution. A prototype was fabricated and the agreement with the simulations study was very good. The measured bandwidth of 34.73%, 48.47%, and 38.21% were obtained, respectively. The gain of 4.02 dBi, 2.47 dBi, and 4.93 dBi was also obtained for each band, respectively. The antenna also presents high efficiency of 53.19%, 49.07%, and 62.21%, respectively. The reported results show that this PIFA is suitable for mobile‐communication applications. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2960–2965, 2016

Multiband Slotted Planar Inverted-F Antenna using Reactive Impedence Surface for Wireless Applicatios

“…The combination of the thickness and feed position of antenna substantially providing at low frequency, increase the bandwidth, change and enhance at the desired frequencies, the gain, and the radiation effectiveness for the resonant frequency bands and the small ultra-thin PIFA with independent power [5]. A planar microstripfed triple-band PIFA is reported for the GSM835, DCS1940, and Wi-Fi 2340 bands [6]. The new design multiband PIFA has simulated cellular phones at different frequency bands is explained in [7].…”
