Compact UWB Antenna With Integrated Triple Notch Bands for WBAN Applications

Abstract

A triple-notch band planar ultra-wideband (UWB) antenna is proposed for wireless body area networks (WBANs) to suppress unwanted signals of conventional narrow band communication technologies. These notch bands are WiMAX (3.3-3.8 GHz), WLAN (5.1-5.825 GHz), and X-band downlink satellite communication systems (7.25-7.75 GHz). A complementary split ring resonator slot and two L-shaped stubs are introduced on an elliptical-shaped radiating patch to obtain UWB coverage from 2.9 to 12 GHz with three notch bands. The overall antenna structure is fabricated on FR4 substrate with a size of 12 mm×19 mm which provides a size reduction of more than 42% with respect to recent literature. The simulated and measured results indicate that the proposed antenna is a good candidate for WBAN applications.

Design of Quad-Port MIMO/Diversity Antenna with Triple-Band Elimination Characteristics for Super-Wideband Applications

“…In contemporary wireless communication, the demand for super-wideband (SWB) and ultra-wideband (UWB) antennas is on the rise [1,2]. The UWB antenna possesses a bandwidth ratio of 3.4:1, and its bandwidth is defined from 3.1 to 10.6 GHz (by the Federal Communications Commission) [3], while the SWB antenna offers a bandwidth ratio of more than 10:1 [4,5].…”

Antennas for UWB Applications

“…One popular commercial application is the wireless USB (WUSB) which is designed to achieve 480 Mbit/s at distances up to 3 m and 110 Mbit/s at up to 10 m. PAN communications involve mobile handheld devices, in which case the used antennas should preferably have omnidirectional patterns with compact size and planar designs [1,2]. Considering that UWB spectrum is shared with other technologies and standards such as the 3.6 GHz IEEE 802.11y wireless local area networks (WLAN) (3.6575-3.69 GHz), 4.9 GHz public safety WLAN (4.94-4.99 GHz), and 5 GHz IEEE 802.11a/h/j/n WLAN (5.15-5.35, 5.25-5.35, 5.47-5.725, 5.725-5.825 GHz), all operating within the Federal Communication Commission (FCC) designated UWB band, of 3.1-10.6 GHz, the design of reconfigurable notch-band antennas has attracted a lot of attention [3][4][5] since they can potentially filter out the unwanted interferer.…”

Design of a novel compact modified‐circular printed antenna for high data rate wireless sensor networks

“…13 Numerous shapes of patch antenna structures have been listed in the literature survey. [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] Mostly used designs of UWB antenna are square, circular, triangle, ring, stepped rectangular, elliptical, pentagon, and hexagonal shapes. From that, circular shapes are widely used for UWB systems and it is suitable for antenna miniaturization.…”
