Radio Frequency Identification (RFID) systems have been extensively used in many important applications in recent years. The band allocated to RFID technology in the UHF band differs from continent to continent but there are two main, 800MHz used in Europe and the some Asian countries while in the USA, Japan and Australia they use 900 MHz frequency ...

Dual-band wearable textile antenna
IEEE Antennas and Propagation Society Symposium, 2004., 2004Future utilization of smart clothing will necessitate applications of multi-function and multifrequency wearable antennas. This work addresses the development of a dual-band textile antenna for wearable applications. The antenna is for GSM operation in the 1900 MHz band and for WLAN operation in the 2.4 GHz band.

Dual-Band WiFi Applique Antenna
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019In this paper, we introduce a dual-band Wi-Fi applique antenna using the 5-mm thick automotive windshield glass as the substrate. In order to mitigate the strong surface-wave supported by the substrate at 5.8 GHz, a segmented ring was proposed to help the antenna radiate out of the substrate at 5.8 GHz while not degrading the performance at 2.4 GHz ...

Miniaturized Dual-Band Implantable Antenna
2018 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2018The main objective of this letter is to present a small-size, dual band implantable antenna operating at the wireless medical telemetry services (WMTS) band (1395–1400 MHz) and Industrial, Scientific, and Medical (ISM) band (2.40-2.48 GHz). A rather compact size of 90mm3( $\mathbf{12\times 12\times 0.625}$ ) is obtained. The simulated -10-dB bandwidths

Printed Dual Band WLAN Antenna
2006 IEEE International Conference on Electro/Information Technology, 2006This paper intends to propose a new and simple printed dual-band planar monopole antenna for Wireless Local Area Network (WLAN) applications in IEEE 802.11 a/b/g. The proposed antenna effectively covers both 2.4/5GHz bands. The antenna comprises of a central arm and two side arm monopoles of different sizes, which generate two separate resonant modes ...

Planar dual-band microstrip antenna
IEEE Transactions on Antennas and Propagation, 1995A novel dual-band microstrip antenna is introduced. The entire structure is planar and can be easily mass-produced by using printed-circuit technology. The antenna consists of multiple layers with metallic strips placed at one of the dielectric interfaces under the radiating patch.

Dual-band quadrifilar helix antenna
IEEE Antennas and Propagation Society International Symposium (IEEE Cat. No.02CH37313), 2003Resonant quadrifilar helix antennas are widely used on hand-held receivers for GPS (Global Positioning System) and for some mobile communication systems. The paper investigates a quadrifilar helix antenna over a ground plane and with trap loading. A model of this antenna was built to operate at two frequency bands, 1227 MHz and 1575 MHz, with more than

Dual-Band Microstrip Patch Antenna
2005 IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications, 2006The purpose of this paper is to develop the microstrip patch designed for dual frequencies of 945 MHz and 1960 MHz. A new design of coplanar patches to get the dual band operation is proposed in this paper. It is a multiple patch approach for getting dual frequency operation with a single feed point.

Dual-band planar monopole antenna
2006 IEEE Antennas and Propagation Society International Symposium, 2006A novel dual-band planar monopole antenna has been proposed. A dual band with wide bandwidth characteristics is observed which covers GSM, DCS, PCS, UMTS, and ISM bands. The results obtained clearly indicate that the proposed antenna is capable of generating good omnidirectional monopole like radiation pattern in all the frequency bands.
