Compact dual-port MIMO filtenna-based DMS with high isolation for C-band and X-band applications
EURASIP Journal on Wireless Communications and Networking, 2023 A dual-port multiple-input multiple-output (MIMO) filtenna with minimal sizes of 80 × 45 mm2 is set up in this study. Each element in this MIMO filtenna is positioned orthogonally to the one next to it to improve isolation.

Compact Ka‐band conical beam filtenna
IET Microwaves, Antennas &Propagation, Volume 17, Issue 3, Page 208-215, February 2023., 2023 A compact conical beam antenna composed by a filtering power divider (FPD) and circular open waveguide is presented. In order to reduce insertion loss in Ka‐band, the five‐way radial power divider and the cascaded filters are constructed using metallic waveguides.

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 ...

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
