In the recent era, fifth-generation technology (5G) has not been fully implemented in the
realm of wireless communication. To have excellent accessible bandwidth feasibility, and in …

This paper presents a compact and simple reconfigurable antenna with wide-band, dual-
band, and single-band operating modes. Initially, a co-planar waveguide-fed triangular …

The proposed work represents a simple and effective approach to achieve frequency
tunability. The tunability is attained by the switching mechanism of the two PIN diodes. The …

In this paper, a novel microstrip feedline-based dual-band frequency reconfigurable
multipleinput multiple-output (MIMO) patch-slot antenna design is presented. The antenna …

This paper introduces the design of a high-gain wideband microstrip patch antenna for sub-
6 GHz 5G communication. The proposed antenna integrates a novel defected ground …
