Systematic Analysis of Rotated Dual‐Split Elliptical SRR with Band‐Stop Characteristics

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2023, Issue 1, 2023., 2023
In this research article, a novel double‐split elliptical split ring resonator (DS‐ESRR) is proposed to achieve frequency‐notching behavior of ultrawideband filtenna, where the semimajor and minor axes of the ellipse are taken as a bivariate random variable and expressed in Ramanujan’s correction coefficient so that more degree of freedom is available ...

Quad-Port MIMO Filtenna With High Isolation Employing BPF With High Out-of-Band Rejection

IEEE Access, 2022
A quad-port multiple-input multiple-output (MIMO) filtenna with compact dimensions of $50\times50$ mm2 is arranged. In this MIMO filtenna, each element is placed orthogonal to its adjacent one to enhance the isolation.

Bandwidth enhancement of antennas designed by band‐pass filter synthesis due to frequency pulling techniques

IET Microwaves, Antennas &Propagation, Volume 16, Issue 1, Page 1-17, January 2022., 2022
Abstract A novel antenna design technique is proposed, which offers bandwidth enhancement up to the limits defined by element radiation efficiency. The employed technique is referred as frequency pulling (FP) as it mimics the ‘insertion loss design methodology of band‐pass filters’.

Design and Study of a Miniaturized Millimeter Wave Array Antenna for Wireless Body Area Network

International Journal of Antennas and Propagation, Volume 2022, Issue 1, 2022., 2022
A miniaturized millimeter wave (mmWave) antenna for wireless body area networks is proposed in this paper. The antenna is found to be operational in the V‐band, around the 60 GHz frequency range, with high efficiency of up to 99.98% in free space simulations. A multilayer, thin substrate was implemented in the design to enhance radiation efficiency and
