Design Ultra-Wideband Antenna have A Band Rejection Desired to Avoid Interference from Existing Bands

Abstract

Ultra-wideband antenna with band notch for rejecting bands. Rectangular slots are introduced on an arborescent patch to get UWB, coverage from 3.1–10.6 GHz. The antenna structure is fancied on FR4 the substrate with a size of 24 mm×24 mm×1.6 mm, a band notch located at 4.7 GHz is generated by adding the rectangular slot on the patch this microstrip antenna is simulated by computer simulation technology, the simulated and manufactured results show the antenna for wireless communication,to reduce the problem of interference in bands in communication systems by using the current distribution techniques, large bandwidths are reduced and unwanted bands are rejected by inserting notch such as rectangular slit and side slot on the patch. The presented antenna, use current redistribution technology, for the antenna designed by adding a rectangular aperture on a rectangular patch to change the current path to a zero value. Despite the fact that these antennas have strong band-notch characteristics and can match the criteria of UWB communication applications.

Development of a Triple Band Notched UWB Antenna

“…The estimation of the notch band frequency for the three notched frequencies, WiMAX, WLAN, and ITU, was calculated using Equation 11 [7]. (11) where…”

“…In recent times, there have been many suggested methods to tackle this important challenge of interference from other applications [9][10][11][12][13][14][15]. In [9], an elliptical complementary split-ring resonator (ECSRR) was reported for frequency notching.…”

“…[10] utilizes quadruple notch slots, filters, and a complementary split ring resonator (CSRR) to form a trapezoidal UWB antenna. A planar UWB antenna with band-notched features was proposed in [11]. A CPW-fed planar UWB antenna with triple band rejection capabilities was created to reduce any potential interference between the UWB system and the narrow band systems.…”

Ultra-wide band antipodal Vivaldi antenna design using target detection algorithm for detection application

“…The majority of the newest detection systems are based on UWB technology. UWB is a broadband technology with a frequency spectrum of (3.1 GHz to 10.6 GHz) that was authorized in 2002 by the "Federal Communications Committee" (FCC) [6], [7]. Numerous attributes, including wide bandwidth, high data speed and good penetration ability have led to the adoption of UWB technology [8], [9].…”

A parametric study on strawberry radiated shaped monopole antenna for ultrawide-band applications

“…Using filters is not a practical solution due to filters complexity of filters, so the proposed antenna will be integrated with the notched filter [17], [18]. Several antenna techniques and patch shapes have been suggested and presented in recent years to obtain UWB response over wide ranges of frequencies.…”
