A dual-band implantable antenna design

2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014
A dual-band implantable microstrip antenna design is proposed for MISC/ISM biomedical telemetry systems. The radiating layer of the antenna is comprised of two concentric square split-ring elements and a metallic pad placed between them. A shorting-pin is also used for miniaturization purposes directly connecting the outer ring element to the ground ...

A Circularly Polarized Dual-Band Microstrip Antenna

IEEE/ACES International Conference on Wireless Communications and Applied Computational Electromagnetics, 2005., 2005
In this paper, we present a dual-band CP patch antenna based on the branch-line coupler feeding technique. The compactness of the dual-band antenna is obtained by inserting a small high-frequency patch into a large low-frequency one. Both patches are printed on the same upper substrate and electromagnetically fed through two perpendicular slots etched ...

Dual band cellular antenna

1997 IEEE MTT-S Symposium on Technologies for Wireless Applications Digest, 2002
Several cellular provider companies have indicated significant interest in a single antenna assembly which could cover both cellular (UHF) and PCS1900 (L-band) frequency bands. A simple, low cost microstrip antenna solution has been developed, demonstrated and the results are presented.

Dual band wearable antenna

2008 Loughborough Antennas and Propagation Conference, 2008
An antenna fabricated using clothing materials is presented. The antenna operates over the wireless network bands at 2.45 Hz and 5 GHz. An electromagnetic band gap surface is used to reduce back radiation by 10 to 15 dB while maintaining the impedance match over the two frequency bands. Coupling between antennas is significantly reduced making it ideal

Dual-band metaloop antenna

2014 International Workshop on Antenna Technology: Small Antennas, Novel EM Structures and Materials, and Applications (iWAT), 2014
This paper presents a metaloop antenna, which radiates a dual-band counter circularly-polarized (CP) wave. The antenna characteristics, including the radiation pattern, gain, and VSWR, are discussed. The radiation efficiency is also discussed. It is found that the gain increases by 3.5 dB for the left-handed CP wave and 4.8 dB for the right-handed CP ...
