Concurrent dual-band LNA for dual-system dual-band GNSS receiver
Analog Integrated Circuits and Signal Processing, 2013Two concurrent dual-band low-noise amplifiers (LNAs) for GNSS applications are presented. They adopted resistive load and LC resonator load, respectively. On-chip circuits are used for biasing the main amplifiers and active baluns are used for single-ended-to-differential conversions.

Dual-band dual-polarization antenna array
2014 International Symposium on Antennas and Propagation Conference Proceedings, 2014This paper is proposed a dual-band dual-polarization antenna array. This antenna is combined by one 2 × 2 dual-polarization patch antenna array and two 1 × 4 dipole antenna arrays operated in ISM 2.4-Ghz/5.2-GHz band. For the purpose to achieve dual band operation, the microstrip line diplexer is applied to combine two antenna operated in 2.4-GHz and 5.

A dual‐band bandpass filter based on dual‐band DBR
Microwave and Optical Technology Letters, 2011AbstractA dual‐band bandpass filter using a new dual‐band dual‐behavior resonator (DBR) structure is proposed.The new dual‐band DBR consists of only two stopband elements connected in parallel. One is a uniform impedance open‐circuited stub and the other is a stepped impedance open‐circuited stub.

IEICE Transactions on Electronics, 2005
This paper presents a dual-band mixer equipped with a dual-band load using current combine technique to minimize chip area by sharing inductors for each frequency band. A systematic design methodology for the current combine load based on parasitic effect considerations is also developed.

A dual-band BPF for concurrent dual-band wireless transceiver
Proceedings of the 5th Electronics Packaging Technology Conference (EPTC 2003), 2004The development of concurrent dual-band wireless transceiver has enhanced the miniaturization of all blocks used in the wireless transceiver. That is achieved by casting the two single-band blocks into a dual-band block. In this paper, a dual-band BPF for the concurrent dual-band wireless transceiver is developed. A stepped impedance resonator (SIR) is

Dual-Band Transmitarrays With Dual-Linear Polarization at Ka-Band
IEEE Transactions on Antennas and Propagation, 2017Dual-band transmitarray antennas are demonstrated at Ka-band with the capability of forming independent linearly polarized beams with a given polarization in each frequency band, while sharing the same radiating aperture. The proposed three-layer unit-cell is based on identical narrow microstrip patches printed on both receiving and transmitting layers

Dual-Band Dual-Mode Antenna with Polarization Diversity
Radioelectronics and Communications Systems, 2021A compact dual-band dual-mode and dual-polarized (DBDMDP) antenna based on an asymmetrical Y-shaped microstrip line feeding along with a square ring radiator is proposed. The structure is loaded with two pairs of L-strips to extend the lower mode bandwidth (center frequency fc = 9.36 GHz).

Dual‐band shorted patch antenna for dual ISM‐band application
Microwave and Optical Technology Letters, 2001AbstractA novel shorted patch antenna with a shorted parasitic patch for dual‐band operation is proposed. The upper and lower operating frequencies are, respectively, controlled by the driven and parasitic patches, which are both operated as a quarter‐wavelength structure in the proposed design. A prototype of the proposed design for achieving dual ISM‐

A dual-band implantable antenna design
2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014A 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 ...
