A Dual-Band Slotted Trapezoidal Inverted-F Antenna for Indoor WLAN Communications
نویسندگان
چکیده
This letter presents a new directional dual-band slotted trapezoidal inverted-F antenna (IFA) for indoor Wireless Local Area Network (WLAN) applications. The dual-band performance can be obtained by tuning the lengths of the inner symmetrical trapezoidal slots and the outer trapezoidal arms in a nearly independent manner. The measured results show that the proposed antenna can provide two separate impedance bandwidths (return loss better than 10 dB) around 180MHz and 750MHz for 2.4/5.1–5.8 GHz WLAN bands, respectively. Good radiation performance and roughly constant in-band antenna directivities are also observed.

Dual Band Slotted Patch Antenna for On/Off-body Communication
Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...
متن کاملA Novel Small E–Ring Shaped Monopole Antenna with Dual Band-Notch Function for UWB Wireless Communications
This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an E-ring shaped radiating patch created and a dual band-notch function can be achieved. The measured bandwidth of th...
متن کاملMulti Attribute Analysis of a Novel Compact UWB Antenna with Via-fed Elements for Dual Band Notch Function (RESEARCH NOTE)
A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...
متن کاملDesign of A Compact CPW-FED UWB Antenna with WiMAX and WLAN Band-Notched Characteristic Evaluated in AHP Framework
In this article, we present a new design of a coplanar waveguide fed (CPW-fed) ultra-wideband (UWB) antenna with dual band-notched characteristics. Two notched frequency bands are achieved by using two inverted U-shaped stepped impedance resonators. The proposed antenna can operate from 2.82 to 11 GHz (118%), defined by VSWR< 2, except two notched bands around 3.5 GHz (WiMAX) and 5.5 GHz (WLAN)...
متن کاملDesign and Study of Uniplanar Coupled Inverted-L Antenna for Single-/Dual-Band Operation
A coupled-line-based planar antenna for single-band and dual-band operation is presented. The well-known uniplanar coupled inverted-L antenna (UCILA) has a simple and specific mechanism to achieve the dual-band ratio that was not described in the past. The UCILA which shunted a short stub in the slotline portion can provide switchable modes among single-low band (3.4% for WLAN 2.44GHz), single-...
