Coplanar waveguide‐fed folded inverted‐F antenna for UMTS application

Abstract

A folded inverted‐F strip antenna printed on a dielectric substrate and fed by a coplanar waveguide is presented. A prototype with a small area of 25×8 mm2 having a 10 dB impedance bandwidth of about 20% centered at about 2.0 GHz has been constructed and studied. The constructed prototype also showed good radiation characteristics, and is suitable for UMTS (Universal Mobile Telecommunication System, 1920–2170 MHz) applications. The experimental results of the constructed prototype are presented, and are also compared with those of a corresponding simple inverted‐F strip antenna. © 2002 John Wiley & Sons, Inc.

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].…”

Novel compact uniplanar printed CPW-fed M-antenna

“…The traditional planar-inverted-F antennas (PIFAs) have attracted interest in the portable device due to their compact planar geometry, easy impedance matching with good radiation efficiency [1][2][3][4][5][6][7]. PIFAs are resonating at approximately /4 resonant length.…”

“…PIFAs are resonating at approximately /4 resonant length. Stacked or folded shorted patch used to enhance the impedance bandwidths in [3] and [4]. In order to achieve multiband operation, slot and parasitic patch are used to obtain multimode resonance in [5] and [6].…”

Compact and Broadband Microstrip Patch Antenna for the 3g Imt-2000 Handsets Applying Styrofoam and Shorting-Posts

“…Electrical requirements for these mobile antennas are sufficient bandwidth, high efficiency, impedance matching, omni-directional radiation patterns, and minimum degradation by the presence of near objects, etc. In general, the size miniaturization of the normal MPA has been accomplished by loading [6,[19][20][21], which can take various forms, namely, 1) Use of high dielectric constant substrates or superstrata; 2) Modification of the basic patch shapes; 3) Use of short circuits, shorting-pins or shorting-posts; and 4) A combination of the above techniques.…”
