Design of a Planar Tri-Band Notch UWB Antenna for X-Band, WLAN, and WiMAX

Abstract

In this work, a new ultra-wideband (UWB) antenna design with 2.08GHz to 12GHz impedance bandwidth and triple-band specifications is presented. The proposed antenna is formed by a truncated square patch, a partial ground plane, and a 50Ω microstrip line. Three different types of slots were used in order to induce notched bands. A C-shaped slot is etched on the radiating patch to obtain a notched band in 3.31-4.21GHz for WiMAX. An inverted U-shaped slot in the micro-strip line induces a second notched band in order to reduce the interference with the WLAN [5.04-6.81GHz]. Finally, two inverted L-shaped slots around the micro-ribbon line on the ground plane allow the X-band [9.13 to 10.75GHz]. The antenna has dimensions of 32×28×1.6mm3. The Ansoft software (HFSS) was used to simulate the proposed structure. The simulation results are in good agreement with the measurement results. The antenna shows an omnidirectional radiation pattern.

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.…”

Circuit Modeling and Analysis of Wearable Antennas on the Effect of Bending for Various Feeds

“…In general, a wearable antenna is stated to have high flexibility and competence in a system connected with the human body. Well-being, health, and lifestyle are the primary interests while implementing these systems [1][2][3][4][5]. Usually, wearable antenna desires for all modern applications must be lightweight, economical, almost maintenance-free, and do not require installation.…”

A Low-Profile Wearable Textile Antenna Using AMC for WBAN Applications at 5.8GHz

“…The use of body-worn electronic devices, such as smart glasses, watches, and textiles, has grown rapidly as a result of the increasing need for wireless communication. The main interests in the implementation of these systems are wellbeing, health, and lifestyle [2]. As a result, Wireless Body Area Networks (WBANs) have attracted considerable attention [3].…”
