Design of SWB Antenna with Triple Band Notch Characteristics for Multipurpose Wireless Applications

Abstract

A compact concentric structured monopole antenna for super wide band (SWB) applications with triple notch band characteristics is designed and experimentally validated. The antenna covers an immense impedance bandwidth (1.6–47.5 GHz) with sharp triple notch bands at 1.8–2.2 GHz, 4–7.2 GHz, and 9.8–10.4 GHz to eliminate interference from co-existing advanced wireless services (AWS), C bands, and X bands, respectively. By loading an E-shaped stub connected at the top of the patch and by etching a split elliptical slot at the lower end of the radiating patch, the band rejection characteristics from 1.8–2.2 GHz for the AWS and 4–7.2 GHz for the C band are achieved, respectively. Further, by making use of a C-shaped resonator near the feed line, band rejection from 9.8–10.4 GHz for the X band is obtained. By varying the parameters of the antenna, the notch bands are controlled independently over a wide range of frequencies. The antenna provides good radiation characteristics, constant group delay response, and better gain over the pass band. The experimental results indicate that the designed antenna offers a remarkable reduction in gain and high variation in group delay over the stop bands. To characterize the wideband property and linear phase response of the designed antenna, its time-domain performance is extensively described and evaluated, which assure pulse transmission with minimum distortion.

Rancang Bangun Antena Monopole Mikrostrip Menggunakan Defected Ground Structure Bentuk Persegi Untuk Optimasi Bandwidth Pada Aplikasi Komunikasi Ultra-Wideband

“…Untuk komponen gelombang mikro dengan Defected Ground Structure (DGS) telah mendapatkan popularitas di antara semua teknik yang dilaporkan guna meningkatkan parameter karena desain struktur yang sederhana (Khandelwal, Kanaujia, and Kumar 2017). Beberapa bentuk celah pada pe-radiasi yang digunakan untuk peningkatan bandwidth, seperti : celah bentuk huruf W, celah bentuk huruf L, celah bentuk huruf T, celah bentuk E dll (Balani et al 2021). Hasil tersebut paling menonjol terhadap bandwidth menonjol adalah celah persegi pada bidang ground (A.…”

An Ultra-Wideband Antenna with Triple Band-Notched Characteristics for Wearable Application

“…Stubs loading onto the antenna structure is a frequently used technique for incorporating notch bands into wideband antennas. Loading the stubs on the radiating patch or ground plane in quadrature transfuses the fundamental frequencies and harmonics, thereby obliterating the intended notch band of frequencies [13]. Other methods have also been used such as by etching various shapes of slots on the radiating patch and/or on the ground, adding folded parasitic strips or resonators in the vicinity of the radiating or the feed line and multiple other techniques.…”

“…Ref. [8] studies a compact concentric structured wideband antenna with triple notch bands was designed and experimentally demonstrated. The antenna exhibited a broad impedance bandwidth of 45.83 GHz (1.67-47.5 GHz) with three notches at 1.8-2.2 GHz, 4-7.2 GHz, and 9.8-10.4 GHz to minimize interference from the AWS, C, and X bands, respectively.…”
