A novel TRI‐band planar inverted‐F antenna for GSM/DCS/PCS operation in mobile handsets

Abstract

In this article, a novel mobile handset planar inverted-F antenna (PIFA) for tri-band operation in GSM, DCS, and PCS bands is presented. This PIFA comprises a rectangular folded planar radiator, which has a J-shaped slot, suspended above a partially grounded substrate. In this antenna, two resonant modes are excited and originate a lower band for GSM and an upper band for DCS and PCS. The influence of several geometrical parameters of the antenna on its performance was investigated to achieve an optimal design. The fabricated prototype of the proposed PIFA has overall dimensions of 45 Â 90 Â 6.6 mm 3 . The measured 10 dB return loss bands of the antenna are 880-892 MHz and 1658-2079 MHz.

Além disso, todo esse sistema complexo deve estar confinado em um produto final leve, de baixo consumo e pequenas dimensões [3]. Para contornar tal problema, uma possível estratégiaé o compartilhamento de mesmas estruturas de recepção/transmissão para bandas distintas.…”

Multiband Operation and Performance Enhancement of the PIFA Antenna by Using Particle Swarm Optimization and Overlapping Method

“…The planar antennas are a generation of antennas boasting the attractive features required; one of them is planar inverted F antenna (PIFA). Because of their small volume, thin profile, and ease of fabrication, PIFAs (planar inverted F antennas) have been shown to be a promising alternative to meet the requirements for mobile handset antennas [2,3]. A PIFA operates at a resonant length of /4; it is highly conducive to a small and lightweight design and suitable for use as an internal antenna [4].…”

Dual band sleeve dipole antenna for WLAN applications

“…Different antennas design engineers proposed different antennas such as PIFA antenna [7], loop antenna [8] and slot antenna [9,10] to provide dual band and multi-band characteristics. Most of the wide band monopoles and side feed dipoles antennas based on wire or microstrip based have very complicated feed system and may require a balanced unbalanced system [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Among all these sleeve dipole antennas provides far better omni-directional radiation pattern and simplicity [1,2].…”
