Small broadband stacked planar monopole

Abstract

A stacked planar monopole, consisting of a top‐loaded element and a parasitic square element, is presented. Its broad bandwidth may be optimized further by cutting two linear slots in the parasite. A size reduction of ∼80% is obtained compared with a conventional square planar monopole. The gain and radiation patterns are also given in this paper. © 2000 John Wiley & Sons, Inc.

Development of Wideband Planar Inverted-F Antennas for Wireless Application

“…Various methods have been proposed for bandwidth enhancement of antennas, including utilization of additive stubs (Ammann and Doyle, 2001;Olmos et al, 2002;Sekine et al, 2004), patterning the ground plane (Wang et al, 2004;Abedin and Ali, 2003),investigating the material proprieties (Ismail et al,2010), meandering the radiating element to achieve multiple resonance frequencies for bandwidth enhancement (Sim and Choi, 2006), slots to achieve wideband impedance matching (Park et al, 2006), using the back side of the substrate (Chen, 2000;Dou and Chia, 2000), changing the feed plate silhouette (Feick et al, 2007), meandering the shorting strip (Chan et al, 2008), adding a radiating element (Il-Young et al, 2010), or by using antenna array (Islam et al, 2007) The aim of this study is to enhance the bandwidth of the planar inverted-F antenna, for this reason and to get a wideband antenna. Firstly we performed a parametric study of PIFA antenna where we have varied the shorting plate width, the feed plate width, the distance between the shorting plate and the feed plate, we studied afterwards the effects of these three parameters of the PIFA on its resonant frequency's impedance bandwidth and radiation pattern.…”

“…In [1], a shorted plate with two folding arms is used, in [2] a shorted patch with parasitic elements, in [3] a shorted monopole with an additional resonator, in [4] where stack monopoles are used or in [5] using a high dielectric constant substrate. These designs, although they manage to cover some frequency bands, have complex structures which make them difficult to manufacture.…”

“…To achieve a reduced antenna height for broad-band or dual-band planar monopole antennas, a variety of designs have also been demonstrated [3]- [6]. These designs include introducing a shorting pin to the planar monopole antenna [3], fabricating the radiating strip of the monopole antenna on a substrate of very high relative permittivity (about 80) [4], using a stacked planar monopole consisting of a top-loaded element and a parasitic square element [5], modifying the geometry of a bent folded monopole/loop antenna [6]. However, the antenna height for these designs is still greater than .…”
