“…Therefore, antenna design with a small size and low cost and ability to operate in multiband for smart-phones is usually a challenge. The planar inverted-F antenna (PIFA) has become the most popular antenna for mobile phones, because it has many outstanding advantages like compact structure, light weight, small size, low manufacturing cost, being integrated with other handset components, good electrical performance, good radiation characteristics, high gain, and low value of the specific absorption rate (SAR), and so forth [3,4]. In addition, several works of literature have proposed miniature structures of multiband PIFA by inserting the slots in the radiating patch and in the ground plane [5][6][7][8][9][10].…”

A new compact multiband PIFA (Planar Inverted-F Antenna) for mobile handset is proposed in this article. The proposed PIFA has a simple geometry with four slots integrated in the radiating patch and ground plane. The PIFA occupies a small volume of 51 × 14 × 7.2 mm3 and is placed on the top portion of mobile phone. The optimized PIFA is worked in the 790 MHz band (737–831 MHz), the 1870 MHz band (1794–1977 MHz), the 2550 MHz band (2507–2615 MHz), and the 3400 MHz band (3341–3545 MHz), to cover LTE700, LTE800, DCS1800, PCS1900, LTE1800, LTE1900, LTE2500, and WIMAX3400 bands. Each of the four operating bands can be controlled independently by the variation of a single parameter of the proposed design, with a wide control range. An omnidirectional radiation pattern to each resonant frequency is obtained with a maximum gain of 2.15 dBi at 790 MHz, 3.99 dBi at 1870 MHz, 4.57 dBi at 2550 MHz, and 6.43 dBi at 3400 MHz. The proposed PIFA is studied in the free space and in the presence of other mobile phone components such as the battery, LCD (liquid crystal display), camera, microphone, speaker, buttons, and a plastic housing. The distribution of specific absorption rate for both European and American standards for each operating band and at various distances between the antenna and the human head is also studied.
