A compact and flexible circularly polarized (CP) wearable antenna is introduced for wireless body-area network systems at the 2.4 GHz industrial, scientific, and medical (ISM) band, which is implemented by employing a low-loss composite of polydimethylsiloxane (PDMS) and silver nanowires (AgNWs). The circularly polarized radiation is enabled by placing a planar linearly polarized loop monopole above...
In this paper a metasurface-based circularly polarized antenna is designed and simulated. The metasurface (MS) loaded with interdigital capacitors and titled slots are proposed to convert linearly polarized (LP) signal from the feeding monopole into circularly polarized (CP) signal radiated at broadside. The MS based antenna has a compact footprint of 0.31λ02 and a thickness of 0.07λ0. According to...
In this paper a newly designed metasurface (MS) loaded miniaturized antenna is proposed and simulated. The double layered MS loaded with complementary split ring resonators (CSRRs) acts as the ground plane for a planar feeding monopole antenna. The antenna has a compact footprint of 0.11λ02 and a thickness of 0.07 λ0. The simulation results show that a wide −10 dB S11 bandwidth of 9% is realized....
In this paper, we present the design, fabrication, and experimental validation of a low-profile and compact metasurface-based conformal wearable antenna operating in the medical body area network (MBAN) band. In particular, a metal backed finite-sized metasurface consisting of a two by two array of I-shaped resonators was employed to replace the conventional ground plane, which enables a low-profile...
In this paper, a compact footprint and low-profile metasurface-enabled unidirectional antenna that operates from 4.11GHz to 4.26GHz with a center frequency at 4.2GHz is presented. The miniaturized metasurface, which has a reflection phase of −150 degree at 4.2GHz, was made possible by interdigital capacitor loading, resulting in a unit cell with an electrical dimension of only 0.02λ02. A finite-sized...
A novel technique to design and optimize a low profile wire antenna with high broadside gain is introduced. The desired antenna properties are achieved by loading an electrically long inverted-F antenna (IFA) with two optimal wire stubs along the body of the antenna. The best lengths and locations of the stubs as well as other antenna design parameters were selected by a new nature-inspired technique...
