Wideband High-Gain EBG Resonator Antennas With Small Footprints and All-Dielectric Superstructures
TL;DR: It is demonstrated that a small superstructure area increases the 3-dB bandwidth of ERAs significantly and more than 85% reduction in the ERA footprint alongside a drastic improvement in bandwidth over the 3%-4% measured bandwidth of the classical single-feed ERAs with unprinted slabs.
Journal ArticleDOI
A Class of Extremely Wideband Resonant Cavity Antennas With Large Directivity-Bandwidth Products
Raheel M. Hashmi,Karu P. Esselle +1 more
TL;DR: In this paper, a single-slab superstrate that has a permittivity gradient in the directions transverse to the antenna axis was proposed for a single feed RCA with a measured 3-dB directivity bandwidth of 52.9% and 16.4-dBi.
Journal ArticleDOI
Recent Advances in Fabrication Methods for Flexible Antennas in Wearable Devices: State of the Art
Bahare Mohamadzade,Raheel M. Hashmi,Roy B. V. B. Simorangkir,Reza Gharaei,Sabih ur Rehman,Qammer H. Abbasi +5 more
TL;DR: An operational perspective of recent advances fabrication methods for flexible antennas is presented, while analyzing the strengths and limitations of each in the microwave as well as millimeter-wave regions.
Journal ArticleDOI
Compact High-Gain Antenna With Simple All-Dielectric Partially Reflecting Surface
TL;DR: In this paper, a simplified approach to design compact, wideband resonant-cavity antennas (RCAs) with partially reflecting surfaces (PRSs) made out of only a single dielectric material is presented.
Journal ArticleDOI
Polydimethylsiloxane-Embedded Conductive Fabric: Characterization and Application for Realization of Robust Passive and Active Flexible Wearable Antennas
Roy B. V. B. Simorangkir,Yang Yang,Raheel M. Hashmi,Toni Bjorninen,Karu P. Esselle,Leena Ukkonen +5 more
TL;DR: The study on polydimethylsiloxane (PDMS)-embedded conductive fabric is presented as a simple yet effective solution to the challenging issue of poor PDMS-metal adhesion, allowing for a relatively easy realization of robust flexible antennas for wearable applications.
