Analysis And Simulation Of Low Profile Planar Inverted - F Antenna Design For WLAN Operation In Portable Devices

International Journal of Scientific & Technology Research, 2016

This paper presents a compact planar inverted–F antenna (PIFA) design for WLAN operation in portable devices. The proposed design has size of 8 x 21 mm and provides peak directive gain of 5.78dBi with the peak return loss of -33.89dB and input impedance of 50.28Ω. It covers a 10dB return loss bandwidth of 410MHz (2.37GHz – 2.789GHz). Its VSWR varies from 1.96 to 1.93 within the antenna return loss bandwidth. As the dimension of the proposed antenna is very small, the antenna is promising to be embedded within the different portable devices employing Wi–Fi applications. This paper includes the return loss as a function of frequency with varying the different parameters, VSWR, input resistance, radiation pattern and current distribution of the proposed antenna.

Novel ultrawideband and multiband triangular planar inverted F antenna for wireless applications

Microwave and Optical Technology Letters, 2007

A novel multi‐ and ultrawideband operation of a single feed triangular antenna are presented. For multi and UWB operation, the proposed design are achieved by inserting U shaped slot on the triangular PIFA with unequal arms, choosing between multi and ultrawide band by adjusting feeding position. Five resonant band of multi band operation is obtained in S‐band, Q‐band, bluetooth band, and WLAN band with acceptable impedance bandwidth. There is an increase in the number of resonant operating frequencies by etching U slot on the shorting feed plate. Ultrawideband is achieved by adjusting coaxial feed to obtained impedance bandwidth 27%. Enhancement impedance bandwidth by using folded shorting plate to improving bandwidth to achieve ultrawide bandwidth around 53%. The proposed antennas have acceptable gain around 11.5 dB. © 2007 Wiley Periodicals, Inc.

An UWB planar inverted-F antenna for wireless applications

2012 IEEE International Workshop on Antenna Technology (iWAT), 2012

The planar inverted-F antenna (PIFA) is widely used in mobile and portable radio systems due to its excellent features. However, it is not yet employed as an ultra wide band antenna because it was considered a narrowband antenna. This paper introduces an ultra wideband planar inverted-F antenna based on three techniques, which are (a) changes in the widths of feed and shorting plates, (b) addition of an inverted-L shaped parasitic element and (c) addition of a rectangular parasitic element. It is shown that ultra wideband PIFAs with fractional bandwidth of more than 100 % is achieved covering from 3.4 GHz to 10.7 GHz. Simulated and measured results are provided to verify the conclusion.

A PLANAR INVERTED F ANTENNA FOR WLAN

New wireless applications requiring operation in more than one frequency band are emerging. Dual-band and tri-band phones have gained popularity because of the multiple frequency bands used for wireless applications. One prominent application is to include bluetooth, operating band at 2.4 GHz, for shortrange wireless use. A dual band small size composite-resonator microstrip antenna configuration for wireless communications is presented in this paper. The proposed antennas, each is built of three resonant elements. Two types of compact short-circuited resonators are used and these are stepped impedance and quarter-wave resonators

Design of Inverted L-slot Ultra-Wideband Antenna

This paper includes a compact sized printed micro-strip antenna (MSA) design which covers the entire ultra-wideband (UWB) ranges from 2 GHz-14 GHz with single wideband notch. A band notch antenna is designed by cutting slots in the radiation element of circular shape radiator patch in order to avoid the potential interference with coexisting wireless local area network (WLAN) systems operating over 5.15-5.825GHz. Here the inverted L-slot is used to provide the desirable wide stop-band to avoid interference with the licensed band. For better performance of the antenna FR4 dielectric substrate with high permittivity () of 4.4 and low loss is used. Radiation pattern is found omnidirectional with Gain more than 3 dB for single band notch operation. The parameters are optimized and simulated in CST Microwave Studio.
