A Review of Various Planar Inverted F- Antenna (PIFA) Structures for Wireless Applications

The recent growth in mobile communication based devices those operate at multiple frequencies has lead to the development of patch antennas that supports multiband and wideband operations. There is an increasing demand for miniaturized and cost effective antenna for both commercial and personal applications. Planar Inverted F Antenna (PIFA) designs support these requirements. The Planar Inverted-F Antenna (PIFA) can be viewed as evolved from a quarter-wavelength monopole antenna and is now widely used in mobile and portable radio applications due to its many attractive attributes such as simple design, lightweight, low-cost, low-profile, conformal nature, built-in structure and reliable performance. In this review paper various designs of PIFA have been presented which are of low profile, high gain and supports multiple frequencies.

Design of Planar Inverted-F Antenna (PIFA) and Study of Ground Plane Effects on its Performance

The design of miniaturized antenna plays a very important role in development of portable communication systems. The resonance frequency, bandwidth and gain of an antenna directly depend on its dimensions. The idea is to find best geometry and structure. The planar inverted –F antenna is very popular for such portable wireless devices because of its compact size and low profile. In this paper, four designs of planar inverted –F antenna (PIFA) with a small square shape radiating element has been introduced to work between 1.67 GHz to 1.8 GHz for UAV, DCS and GSM applications. These antennas are low cost simple in design and easy to fabricate. The bandwidth provided by the PIFA is wide as compared to a conventional micro strip patch antenna of half wavelength. The dimensions of antenna have been optimized to have a wide bandwidth (9.47 %) with air as dielectric used in this design. The effect of different ground plane sizes has been analyzed. The results will be very useful in the design of PIFA for applications requiring a small ground plane. Simulated and measured results are presented for smallest structure.

Design of Novel Structured Triband PIFA for Mobile Application

A planar inverted-F antenna with a huge bandwidth starting from 817MHz to 11.5 GHz proposed as an substitute for high concert mobile phones proposed to cover the major part of the mobile phone frequencies global as well as the multi wideband frequency range. A prototype of the antenna was construct and the reflection coefficient and radiation patterns were measured to display an adequate radiation performance. Besides, the easy creation without a matching network or a difficult geometry is an supplementary attribute that can be reflected in low invention cost

Design and Analysis of Planar Inverted-F Antenna for Wireless Applications

A tri-band planar inverted-F antenna (PIFA) for wireless applications has been presented in this paper. The proposed antenna is compact in size and design on FR4 substrate. The antenna consists of a slotted radiator supported by shorting wall and a small ground plane. Slots in radiating patch have been used to introduce multiband operations into the proposed antenna. The structure is designed and optimized to operate at 2.02GHz, 3.06GHz and 6.1GHz with achievable bandwidths 13.5%, 10% and 16% respectively. These three bands cover the existing wireless communication frequency bands from 1.8- 6.6 GHz. The effects of feed position and shorting wall on return loss, bandwidth, VSWR and gain have been analyzed. Good return loss, antenna gain and radiation pattern characteristics are obtained in the frequency band of interest. Structural dimensions of the proposed antenna are optimized by using HFSS EM solver. Details of the tri-band PIFA characteristics are presented and studied.
