摘要

本文设计了一种紧凑的花形cpw馈电天线，用于多波段应用。该天线是通过在八边形的边缘上添加圆形分形元素来创建的，并且创建了一个具有类似结构的较小尺寸的槽，该槽负责多波段共振。该天线尺寸为25 mm × 25 mm，结构紧凑，具有2.82 ~ 6.43 GHz、7.36 ~ 8.52 GHz、11.21 ~ 12.2 GHz和14.05 ~ 15.83 GHz四个共振频段。讨论了各种天线特性参数，如回波损耗、驻波比、阻抗、辐射方向图、电流分布、衬底材料性能等。天线设计可用于不同的应用，如WiMAX (IEEE 802.16)、WLAN (IEEE 802.11b、802.11a/g)、INSAT、固定卫星、ITU频段、x频段卫星通信、电视广播、BSS、FSS和ku频段。

A compact CPW-fed wideband antenna with circular fractal elements for multiband operations

In this article, a compact flower-shaped CPW-fed antenna is designed for a multiband application. The proposed antenna is created by adding circular fractal elements to edges of the octagon and a slot is created with a similar structure of smaller dimension which is responsible for multiband resonance. The antenna has a compact size of 25 mm × 25 mm, and it exhibits four resonance frequency bands at 2.82 to 6.43 GHz, 7.36 to 8.52 GHz, 11.21 to 12.2 GHz, and 14.05 to 15.83 GHz, respectively. Various antenna characteristics parameters like return loss, VSWR, impedance, radiation pattern, current distribution, substrate material properties are discussed. Antenna design can be used for different applications such as WiMAX (IEEE 802.16), WLAN (IEEE 802.11b, 802.11a/g), INSAT, fixed satellite, ITU band, X-band satellite communication, TV broadcasting, BSS, FSS, and Ku-band.
