Self-Decoupled Dual-Band Shared-Aperture Base Station Antenna Array
IEEE Transactions on Antennas and Propagation, 2022A new decoupling concept for dual-band shared-aperture base station antenna arrays is proposed. By loading arrow-shaped decoupling structures in the hollowed regions of the low-band (LB) loop dipole arms, the LB antenna can yield partial reflection to ...

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

Dual-Band Dual-Polarized Patch Antenna Using Characteristic Mode Analysis
IEEE Transactions on Antennas and Propagation, 2022In this research, a novel dual-band triangular patch antenna (TPA) with linear-orthogonal polarization is designed by utilizing degenerate modes (DMs). Current symmetries of fundamental DMs of TPA are exploited to achieve dual-band antenna operation.

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.
