Pentagonal Shaped Uwb Antenna Loaded With Slot and Ebg Structure for Dual Band Notched Response

Abstract

In this paper, a planar, compact, and low cost printed microstrip line fed pentagon-shaped ultra-wideband antenna offering dual band notched characteristics response is proposed and investigated. By introducing modified V-shaped slots in the pentagonal patch and hexagonal electromagnetic band gap structures near the feedline, dual band notched response can be realized. The proposed antenna is successfully simulated, designed, and fabricated on an FR-4 substrate. The measured results show that the proposed antenna having dimensions of 35 × 33 × 1.6 mm 3 has a bandwidth over the frequency band 2.7-10.6 GHz with magnitude of S 11 ≤ −10 dB (VSWR ≤ 2), except 3.7-4.6 GHz (C-band Satellite Communication) and 5.16-6.08 GHz (WLAN) frequency bands. The presented antennas show small group delay variation, nearly omnidirectional radiation pattern and stable gain at working frequencies. Satisfactory results have been obtained in frequency and time-domain analysis of the proposed antenna. The formulation of the center frequency of dual notched frequency band is also proposed.

Design of Penta-Band Notched Uwb Mimo Antenna for Diverse Wireless Applications

“…A compact two port MIMO antenna which comprises two octagonal shape elements with a stub on ground and a slot on patch to reject duple band frequencies is reported in [37] for the rejection of most of the EM interference. By incorporating v-shape slots on pentagonal shape patch and a hexagonal shape EBG next to the feed, dual notches are achieved in [38]. A CPW-fed 4-port MIMO antenna which consists of TSESC patches for the elimination triple frequencies is introduced in [39].…”

Design and Analysis of a Compact Uwb-Mimo Antenna With Four Notched Bands

“…In this regard, the study of UWB-MIMO antennas with properties of notched band (NB) and low MC is conducive. Some techniques of developing NBs for UWB antennas have been introduced in [4][5][6][7][8][9][10][11][12][13]. A U-shaped slot, an elliptical slot, and two pairs of quarter-wavelength stubs are used to generate a notch in [3][4][5], respectively.…”

“…Refs. [6][7][8] realized dual NBs, in which a slot and EBG structure was used in [6], an I-shaped and C-shaped stubs in [7], a C-shaped slot and complementary split-ring resonator (CSRR) in [8]. Triple NBs were produced in [9,10].…”

Performance Analysis of Wearable Dual-Band Patch Antenna Based on EBG and SRR Surfaces

“…In this design, holes were introduced for shunt inductance, which is difficult to fabricate in practical applications [ 29 ]. In contrast to the EBG structure, different researchers have carried out research involving SRRs in the UWB spectrum for dual-band-notched responses [ 30 ]; developed SRR sensors to detect the permittivity of liquid [ 31 ]; and developed SRR metamaterial for pass band and stop band characteristics [ 32 ].…”

“…This work extends our previous design in [ 33 ] and provides a much improved design. Considering the poor performance of recently reported designs [ 24 , 25 ], due to low gain and bandwidth or lack of practicability in the improved designs in [ 28 , 30 ], the objective of this work is to provide a promising solution for wearable applications. The unique work in this paper consists in the analysis of an EBG structure-based antenna and its comparison with SRR for different design parameters.…”
