Frequency and Time Domain Analysis of Triple Band Notched Uwb Antenna With Integrated Bluetooth Band

Abstract

This paper presents the time and frequency domain analysis of a compact tri-band notched UWB (ultra-wideband) antenna with integrated Bluetooth frequency for wireless applications. Modifications in radiating element and DGS techniques are used to achieve high impedance bandwidth. The antenna operates at UWB frequency band 3.1-10.6 GHz as well as Bluetooth frequency 2.4 GHz. The band notch characteristics are at Wi-MAX (3.3-3.7 GHz), WLAN (5-6 GHz), and X-Band Satellite communication (7.1-7.76 GHz). These notches are obtained by etching different slots in the ground plane and radiating elements. Gain, group delay, pulse transmission, and radiation patterns of the proposed antenna are also investigated. A prototype of the antenna is fabricated, and the reflection coefficient is measured. A comparison has been made between the proposed antenna and previously published UWB antennas.

A novel foot‐shaped elliptically embedded patch‐ultra wide band antenna with quadruple band notch characteristics verified by characteristic mode analysis

“…Recently, it has become important to create a multinotch band antenna. To achieve WiMAX and WLAN dual band notches, an I‐shaped and C‐shaped stubs are embedded into the patch, 5 by using pin diodes WiMAX and WLAN notched bands that are obtained in Azim et al 6 The WiMAX/C, WLAN, and X‐band triple band notches are reported in earlier studies 7–9 . In Alotaibi and Alotaibi, 7 one C‐type, U‐type, and L‐type slits are used to notch interference due to WiMAX, WLAN, and X‐band.…”
