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 ...

The Application of Reconfigurable Filtennas in Mobile Satellite Terminals [PDF]
IEEE Access, 2020 Reconfigurable antennas play an important role in wireless communication systems as the physical and electrical properties of their structures can be modified, allowing them to be used in different applications. In this paper two reconfigurable filtennas are presented to integrate mobile devices that communicate (uplink and downlink) with satellites in

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

Reconfigurable and Tunable Filtenna for Cognitive LTE Femtocell Base Stations [PDF]
International Journal of Microwave Science and Technology, Volume 2016, Issue 1, 2016., 2016 A single‐port uniplanar antenna with a built‐in tunable filter is presented for operation in multiple LTE bands for cognitive femtocell applications. The antenna is based on a monopole microstrip patch fed by coplanar waveguide. The frequency reconfigurability is achieved by using two PIN diodes to couple or decouple a ring slot resonator filter from ...
