“…Current mobile handsets require antennas that are compact, lightweight, low cost, efficient, and able to operate in multiple frequency ranges. In this context, the planar inverted-F antenna (PIFA) can be considered as a suitable alternative for meeting the needs of cell phones, which is demonstrated by several PIFA designs found in the literature [1][2][3][4][5][6][7][8][9].…”

“…Furthermore, small antennas that exhibit high efficiency and good impedance matching in multiple frequency bands are difficult to design [12]. Therefore, a minimum returnloss level of 6 dB (voltage standing wave ratio (VSWR) = 3.0) or 7.3 dB (VSWR = 2.5) within the operation bands is often accepted for antennas in mobile handsets [1][2][3][4][5][6][7][8]12], which is lower than the traditional limit of 10 dB specified for most common applications.…”

This study presents a planar inverted‐F antenna for penta‐band operation in portable devices, in accordance with the following wireless communication standards: global system for mobile communications, digital cellular system, personal communications service, universal mobile telecommunications system, and wireless local area network. The proposed antenna consists of a folded planar radiator with two slots – a J‐shaped and a rectangular one – suspended above a substrate partially covered with a ground plane, to which a printed radiating strip is connected. Multiple resonances excited in this structure generate the radiation bands of the antenna, covering all required frequency ranges. A parametric analysis is conducted with the aid of electromagnetic simulation in order to evaluate the influence of geometrical dimensions of the antenna on its performance. The fabricated antenna prototype exhibits overall dimensions of 45 mm × 90 mm × 6.6 mm, and the experimental 10 dB return‐loss bands of the antenna are 869–966, 1653–2200, and 2390–2505 MHz, with a measured linearly polarised gain of 2.2 dB at 915 MHz, 2.0 dB at 1900 MHz, and 1.0 dB at 2450 MHz, on the principal cut planes. A good agreement is observed between simulated and experimental results.

“…To achieve the requirements, several multiband and wideband antennas for mobile handsets applications have been reported, such as inverted-F antenna (IFA) [1][2][3] and planar inverted-F antenna [4][5][6][7][8][9][10][11][12]. Although both IFA and PIFA are multiband compact antennas with quarter wavelength structure, suitable for conventional mobile handsets, they exhibit additional height in addition to the substrate thickness which gives system design complexity.…”

In this paper, a compact wideband planar monopole antenna suitable for slim mobile handsets applications is presented. The proposed antenna operates over LTE700/GSM800/900 (0.742 GHz-1.36 GHz), GPS L1/GSM1800/1900/UMTS/IMT2100/Wi-Fi/LTE2300/2500 (1.475 GHz-2.7 GHz), and WiMAX (3.4 GHz-3.72 GHz) based on reflection coefficient better than −6 dB. It consists of coupling strip, shorted radiating strip, and parasitic meandered lines. The wider impedance bandwidth is achieved by placing the meandered line as parasitic element on the back side of the coupling and shorted radiating elements. With this configuration, the antenna gives extremely wide impedance bandwidth which covers all the required frequency bands of the smart mobile phones. To investigate the proposed antenna, S-parameters, surface current distributions, and radiation performances are studied.To check the robustness of the proposed antenna, investigation is also carried out in the vicinity of the mobile environment. Further, specific absorption rate (SAR) is calculated on the human head and found to be below 0.535 W/kg. The simulated and measured results are found in close agreement.

“…By the way, the PIFA has the critical problem, which the impedance bandwidth of conventional PIFA is narrow. So, many techniques of internal antennas to improve the impedance bandwidth have been studied to meet the needs for multiband and multimedia handset antenna for the third generation mobile system, such as the stacked patch type PIFA [1], combination antenna of PIFA and planar inverted-L (PIL) [2][3][4], electro-magnetic feeding antenna type using ground slit and slot [5][6][7], monopole antenna type [8][9][10][11][12][13][14], and PIFA type using variation of feeding structure [15].…”

Abstract-In this paper, we propose a wideband internal Planar Inverted-F Antenna (PIFA) by novel feeding structure at practical mobile handset. The proposed antenna by novel feeding structure shows 33.49% wideband impedance bandwidth, compared to 16.92% impedance bandwidth of normal feeding structure of PIFA. We explain novel feeding structure antenna by using equivalent circuit. The normal feeding structure of conventional PIFA has the inductive reactance structurally. To reduce its inductive reactance, a shunt inductive reactance using a novel feeding structure is added to normal feeding structure of conventional PIFA, structurally. So, reactance of PIFA is decreased and impedance bandwidth of PIFA is increased. The size of proposed antenna is 29.2 × 8.2 × 8.3 mm 3 . As well as, the implemented antenna has a good radiation pattern and high antenna gains despite very small volume.
