A Shared-Aperture Dual-Band Dual-Polarized Filtering-Antenna-Array With Improved Frequency Response [PDF]
IEEE Transactions on Antennas and Propagation, 2017 In this paper, a novel dual-band dual-polarized (DBDP) array antenna with low frequency ratio and integrated filtering characteristics is proposed. By employing a dual-mode stub-loaded resonator (SLR) to feed and tune with two patches, the two feed ...

A Circularly Polarized Dual-Band Microstrip Antenna
IEEE/ACES International Conference on Wireless Communications and Applied Computational Electromagnetics, 2005., 2005In 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 ...

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

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 ...

Dual‐band planar inverted‐F antenna
Microwave and Optical Technology Letters, 2003AbstractA new kind of planar inverted F antenna (PIFA) is presented. To reduce the size of the structure, the resonator has been curled under itself. A capacitive load is added to decrease the frequencies of higher resonances. The result is the achievement of a dual‐band antenna. Theoretical results are computed by the software design package IE3D. The
