A Fractal Monopole Antenna With Dual Polarization Reconfigurable Characteristics for X-Band Applications
Autor: Sashi Shankar, Dileep Kumar Upadhyay
Publikováno v: IEEE Access, Vol 11, Pp 95667-95680 (2023)
A monopole antenna with dual (linear/circular) polarization reconfigurability for X-band applications is presented in this paper. The antenna consists of a bent arm cross-shaped (BACS) slot created on the inverted triangular staircase fractal (ITSF)

A Compact UWB Bandpass Filter using Hybrid Fractal Shaped DGS
Autor: Babu Lal Shahu, Neela Chattoraj, Srikanta Pal, Dileep Kumar Upadhyay
Publikováno v: Journal of Microwaves, Optoelectronics and Electromagnetic Applications, Vol 16, Iss 1, Pp 38-49
Abstract In this paper, a novel and compact ultra wideband (UWB) bandpass filter (BPF) based on fractal-shaped defected ground structure (DGS) is designed and developed. It is made of stepped impedance lines and a composite right/left handed-transmis

Design of a Compact UWB Bandpass Filter using Via-Less CRLH TL
Autor: Dileep Kumar Upadhyay, Uday Kumar, Gajendra Kant Mishra, Babu Lai Shahu
Publikováno v: Journal of Microwaves, Optoelectronics and Electromagnetic Applications, Vol 16, Iss 2, Pp 336-350
Abstract A novel compact ultra wideband (UWB) bandpass filter (BPF) based on composite right/left handed transmission line (CRLH TL) is reported in this paper. The proposed UWB BPF is designed and developed by coupling of two unit-cells of via-less C

An improved zeroth order resonator using left handed metamaterial
Autor: Dileep Kumar Upadhyay, Srikanta Pal
Publikováno v: Journal of Microwaves, Optoelectronics and Electromagnetic Applications, Vol 12, Iss 1, Pp 131-140
In this paper an improved version of zeroth order resonator (ZOR) using Left Handed Metamaterial (LHM) is reported, and its performance is compared with the earlier published ZOR. The resonator is designed based on microstrip technology using composi

A compact parallel coupled meander lines shaped composite right/left-handed transmission line (CRLH-TL) based symmetric quasi-0 dB coupler
Autor: Dileep Kumar Upadhyay, Srikanta Pal, Abhishek Kumar
Publikováno v: Frequenz. 74:295-307
In this paper, parallel coupled meander lines (PCML) composite right/left-handed transmission line (CRLH-TL) based symmetrical quasi-0 dB coupled-line coupler is presented. Proposed coupler shows measured backward wave coupling level of 0.81 dB at fr

Design of the quasi-0 dB backward wave-coupled line coupler using CRLH-TL based on stepped-impedance open stub-loaded dual-mode resonator
Autor: Srikanta Pal, Abhishek Kumar, Dileep Kumar Upadhyay
Publikováno v: Journal of Electromagnetic Waves and Applications. 34:849-868
This paper demonstrates symmetric backward wave quasi-0 dB coupled line coupler (CLC) based on the globe shaped composite right/left-handed transmission line (GS-CRLH-TL). The proposed CLC shows qu...
