Portable communication devices such as WLAN, WiMAX, LTE, ISM, and 5G utilize one or
more of the triple bands at (2.3–2.7 GHz, 3.4–3.6 GHz, and 5–6 GHz) and suffer from the …

Empirical results of an electrically small printed monopole antenna are described with a
fractional bandwidth of 185%(115 MHz to 2.90 GHz) for return‐loss better than 10 dB, peak …

This paper presents a radiofrequency (RF) energy harvesting system based on an
ultrawideband Archimedean spiral antenna and a half-wave Cockcroft-Walton multiplier …

An electrically small antenna ensures easy integration with devices without compromising
the form factor. The performance in terms of bandwidth, gain and so on for these antennas is …

A novel antenna design was configured via a five‐stage process. At each stage, a new
modified square patch with a half size of that used in the previous stage was added to shape …

This article presents a novel antenna design that consists of a butterfly-shaped radiator, the
ground, and the slot between them. A lumped element of resistance was inserted between …

This work presents the design, manufacturing, and measurement of a miniaturized circularly
polarized ultrawideband Archimedean spiral antenna that operates from 0.3 GHz to 16 GHz …

The development of communication technology and the expansion of spectrum have
brought the urgent demand for antenna miniaturization. In this letter, a method of …

In this paper, performance enhancement in a shorted polygonal archimedean spiral antenna
has been proposed by backing it with a hybrid reflector. In the proposed work, two arms of …

Bio-inspired Dielectric Resonator Antennas (DRAs) are engaging more and more attention
from the scientific community due to their exceptional wideband characteristic, which is …
