A Novel Circuit Combining a Dual-Band Antenna with a RF Diplexer for Concurrent Dual-Band RF Energy Harvesting Applications

2020 International Conference on Green and Human Information Technology (ICGHIT), 2020
This paper proposes a circuit structure consisting of an RF diplexer and a dual-band antenna for RF energy harvesting applications. The dual-band antenna was fabricated on microstrip line using a FR4 substrate. The RF diplexer was implemented using lumped components.

Implicit space mapping method for dual-band filter and wideband diplexer design

2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2016
In this paper, open-stub loaded resonator and short-stub loaded resonator are adopted to design a novel wideband diplexer and dual-band filter. To accelerate simulation speed, implicit space mapping method is firstly applied in multi-mode filter and diplexer design.

Dual-Band Self-Diplexed Modulated Metasurface Antennas

12th European Conference on Antennas and Propagation (EuCAP 2018), 2018
This paper presents a simple and effective technique to design dual-band modulated metasurface (MTS) antennas. In MTS apertures, an equivalent surface inductance supports the propagation of a transverse magnetic (TM) surface wave (SW). The SW power can be gradually radiated at one frequency by periodically modulating the surface reactance.

Compact SIW Diplexers and Dual-Band Bandpass Filter With Wide-Stopband Performances

IEEE Transactions on Circuits and Systems II: Express Briefs, 2020
A realization method of wide-stopband substrate-integrated waveguide (SIW) diplexers and dual-band bandpass filters (BPFs) with widely realizable frequency ratios is presented using modified intrinsic modes suppression technique. Design procedures of dual-band and wide-stopband characteristics for different frequency ratios are systematically ...

Compact Waveguide Dual-Band Filters and Diplexers

IEEE Transactions on Microwave Theory and Techniques, 2017
This paper presents a new class of dual-band filters and diplexers, realized based on dual-band resonators. The proposed dual-band filter and diplexer do not require junctions and can achieve equivalent performance with fewer cavities, thus offering a significant reduction in size compared with traditional approaches.

A compact waveguide diplexer employing dual-band resonators

2014 IEEE MTT-S International Microwave Symposium (IMS2014), 2014
This paper outlines a new class of diplexers realized using a combination of dual-band cavities and single-band cavities. The proposed diplexer does not require junctions and can achieve similar performance with fewer cavities, thus significantly reducing the size of the diplexer when compared to traditional approaches.

Design of a compact dual-band diplexer with dual-mode cavities

2012 42nd European Microwave Conference, 2012
In this paper, we propose a compact dual-band microwave output diplexer for the next generations of communication satellite. For reducing bulk, the designed diplexer is exclusively composed of coupled resonators and channel filters realize dual-band filtering functions.

A self-diplexing dual-band planar array for GNSS applications

2015 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2015
A planar dual-band sequentially-rotated array is proposed to cover the radionavigation bands at 1.19 and 1.57 GHz. The antenna consists of a two-port ring microstrip line that series feeds four radiating elements. The basic radiator is the so-called complementary strip-slot, a microstrip-fed slot that has its complementary stub superimposed to it on ...

Design of microstrip dual-band filters using a double- diplexing configuration

2006 Asia-Pacific Microwave Conference, 2006
Two microstrip filters are diplexed at the input and output ports to realize a dual-band characteristic. The center frequencies, bandwidths and orders can be quite arbitrary since the two individual filters are realized independently. T- junctions are used to connect filters in parallel and extended microstrip arms are added to each filter for ...

Design of a New Dual-Band Diplexer for GPS, WLAN and WiMAX Applications

Journal of Electromagnetic Waves and Applications, 2012
Abstract In this paper, a dual-band diplexer is proposed. Two dualband bandpass filters (DB-BPFs) using coupled stepped-impedance resonators (SIRs) operated at 1.575/2.13 GHz and 3.15/5.2 GHz are main blocks combined with a branch matching circuit for the proposed dual-band diplexer. By analyzing the input impedance Zin of different loading structures,
