“…11, it can be roughly explained that the inner part of this structure (slot) provides high frequency component of dual-band, whereas the outer part provides a low frequency component. Several PIFA antennas and their extended versions are reported for multiband operations including triple band (Manteghi & Rahmat-Samii, 2006), quad band (Ciais et al, 2004) and even six-band (Guo & Tan, 2004) for mobile communication systems. In (Manteghi & Rahmat-Samii, 2006), a compact triple band PIFA operating in WLAN 2400 (2.4-2.5 GHz) band and two different UNII bands (5.15-5.35 GHz and 5.7-5.85 GHz) is presented.…”

“…The proposed antenna provides return loss higher than 10 dB for the mentioned bands. The paper presented in (Ciais et al, 2004) uses several multiband techniques such as multiple resonant structures (cutting slots) and parasitic resonators in order to implement a quad band PIFA. This antenna covers GSM 900 band by providing VSWR less than 2.5 and GSM 1800, 1900 and UMTS bands by providing VSWR less than 2.…”

“…Several researches have contributed to designing multi-band antennas. Different techniques for designing multi-band antennas such as adopting multibranched strips [2,3] and adding parasitic elements to resonate at different frequencies in a single radiating device [4,5]. However, these solutions generally suffer from certain drawbacks including a large volume and large ground plane.…”

Abstract-In this paper, a nonlinear phase enhancement of multi-resonance composite right/lefthanded unit cell for multi-band antennas is presented. Different antennas with nonlinear enhanced phase which can operate up to five different frequency bands are introduced. Meanwhile, the proposed antennas have compact size so that they can demonstrate size reduction up to 60% compared to conventional patch antennas operating at the same frequencies. The achieved phase enhancement has been validated by comparing two different configurations of composite right/left-handed cells. The analysis, electromagnetic full wave simulations and experimental results are discussed. A reasonable agreement is achieved between the measured and simulated results.

“…Tri-band, quad-band, penta-band or hexa-band antenna can be found in many journals (Chiu & Lin, 2002;Guo et al, 2003Guo et al, , 2004Ciais et al, 2004;Bancroft, 2005;Ali & Hayes, 2000;Soras et al, 2002;Nepa et al, 2005;Wong et al, 2005;Liu & Gaucher, 2004Wang et al, 2007). For example, Chiu presented a tri-band PIFA for GSM800/DCS1800/PCS1900 in 2002 (Chiu & Lin, 2002) .…”

“…proposed a compact internal quad-band for covering GSM900/DCS1800/PCS1900 and ISM2450 bands (Guo, et al, 2003). By adding three quarter-wavelength parasitic elements to create new resonances, Ciais et al presented a design of a compact quad-band PIFA for mobile phones (Ciais et al, 2004). In 2004, Guo & Tan proposed a new compact six-band but complicated internal antenna.…”
