“…Where 𝐶 is the speed of light, 𝑊𝑝 and 𝐿𝑝 are the width and length of the top plate of the PIFA, and 𝑓 0 is the resonant frequency [20]- [22]. The configuration of a PIFA antenna is very simple and easy to design, and the addition of a slots such as 𝑈 slot or 𝐿 slot in the radiating element bring back other resonances [4].…”

This paper presents the design of a reconfigurable planar inverted-F antenna (PIFA). The proposed antenna is designed and optimized to operate in two frequency bands. 2.4 GHz allocated to the industrial, scientific and medical (ISM) band for the identification of a set of vehicules within a given area, and 1.575 GHz allocated to the global positioning system (GPS) band to locate them outside. The ISM band is used for microwave frequencies for active radio frequency identification (RFID) tag, which is associated with the object to be identified. This antenna consists of two radiating elements connected by a positive-intrinsic-negative (PIN) diode to obtain the frequency reconfigurability. The first radiating element is connected to the ground plane by a shorting pin and excited by a 50 Ω coaxial feed line. Its total size is 30 mm × 50 mm × 7 mm. The substrate used is FR4 with constant dielectric relativity of 4.4 and a height of 1.6 mm. Computer simulation technology microwave studio (CST MWS) software is used to simulate and optimize the proposed reconfigurable PIFA antenna.

“…The shorting pin also helps match the antenna impedance to the feeding/receiving circuit impedance. The PIFA is an attractive antenna for systems where the space volume of the antenna is limited as the antenna size is in the order of \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} }{}$\lambda/4$ \end{document} [16] , [17] . There are no typical equations for designing the PIFA.…”

Design of a rectangular spiral planar inverted-F antenna (PIFA) at 915 MHz for wireless power transmission applications is proposed. The antenna and rectifying circuitry form a rectenna, which can produce dc power from a distant radio frequency energy transmitter. The generated dc power is used to operate a low-power deep brain stimulation pulse generator. The proposed antenna has the dimensions of 10 mm \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} }{}$\times\,$ \end{document}12.5 mm \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} }{}$\times\,$ \end{document}1.5 mm and resonance frequency of 915 MHz with a measured bandwidth of 15 MHz at return loss of \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{upgreek} \usepackage{mathrsfs} \setlength{\oddsidemargin}{-69pt} \begin{document} }{}${-}{\rm 10}~{\rm dB}$ \end{document}.

An L-section impedance matching circuit is used between the PIFA and voltage doubler rectifier. The impedance matching circuit also works as a low-pass filter for elimination of higher order harmonics. Maximum dc voltage at the rectenna output is 7.5 V in free space and this rectenna can drive a deep brain stimulation pulse generator at a distance of 30 cm from a radio frequency energy transmitter, which transmits power of 26.77 dBm.

“…1 shows a basic PIFA structure which is fed at the base by a feed wire. In a PIFA structure there are several design variables which can be varied and the performance of the desired antenna is achieved [5]- [6]. Some of the design variables are width, length and height of the top radiating patch, width and position of shorting pin or plate, location of the feed point, dimensions of the ground plane.…”

This paper proposes a novel low SAR multi-band PIFA structure with reduce exposure of the human head to mobile-set antenna radiation. Triple band PIFA structure operating at GSM 900, GSM 1900 and Wi-Fi bands are designed and fabricated .Analysis of SAR is SAR is decreased by reducing the radiation towards human head ,while maintain significant radiation in all other directions. This SAR reduction is accomplished by inserting suitable slots in the top radiating patch and ground plane of PIFA at appropriate positions so as to modify the current distribution and radiation pattern. Keywords -PIFA, internal antenna, FR4 dielectric, planar element, return loss, VSWRI.
