Dual-Mode Dual-Band Filter With Band Notch Structures
IEEE Microwave and Wireless Components Letters, 2010A novel approach for designing dual-mode dual-band bandpass filters is proposed and experimentally studied. By embedding a pair of slits in the square patch, the dual-band response is realized and one transmission zero is introduced between the two passbands.

A Novel Dual-Band Branch Line Coupler for Dual-Band Butler Matrix
IEEE Transactions on Circuits and Systems II: Express Briefs, 2019In this brief, a novel dual-band branch line coupler (BLC) for designing a dual-band Butler matrix (BM) has been proposed. To realize the proposed BLC, a unique dual-band impedance transformer (DBIT) with a derivation of closed-form design equations, capable of performing a dual-band operation for a traditional transmission line (TL) of any electrical ...

Dual-band dual-polarized transmitarrays at Ka-band
2017 11th European Conference on Antennas and Propagation (EUCAP), 2017Transmitarray antennas with dual-band and dual-polarization capabilities are studied here numerically. The antennas are designed based on linearly-polarized unit-cells working at Ka-band for satellite applications. The unit-cells include two printed patches and a connecting via; a 180° phase shift is obtained by rotating one of the patches.

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.
