Simple Dual Band Rectifier Based on Diplexer for Ambient RF Energy Harvesting Application

2020 11th IEEE Annual Ubiquitous Computing, Electronics & Mobile Communication Conference (UEMCON), 2020
In this paper, we present a novel configuration of dual band rectifier for RF energy harvesting application. Unlike traditional dual band rectifiers which employ only one rectifier with the ability to operate at two different frequencies, the proposed design consists of two separated rectifiers, each operates at a distinct frequency, thus simplify the ...

Novel high-rejection LTCC diplexers for dual-band WLAN applications

IEEE MTT-S International Microwave Symposium Digest, 2005., 2006
This paper presents novel highly-integrated LTCC diplexers for dual-band Wireless-LAN (IEEE 802.11 a/b/g) appli- cations. Two diplexer versions with integrated high-rejection filters have been realized and optimized for the receive and for the transmit mode. The measured results demonstrate excellent performance.

A Diplexing Antenna for Dual-band Dual-Sense Operation wih High Isolation

2020 9th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2020
A diplexing antenna with dual-band dual-sense circularly polarization is presented. The antenna is composed of two square patches with reverse truncated corners. High isolation and low frequency ratio of 1.09 are achieved by loading filtering structures on feeding networks. The stacked configuration is compacted and suitable for satellite communication

A novel integrated Tx-Rx diplexer for dual-band WiMAX system

2010 IEEE MTT-S International Microwave Symposium, 2010
In this paper, a novel integrated Tx-Rx diplexer for dual-band Worldwide Interoperability for Microwave Access (WiMAX) application is realized by low temperature co-fired ceramic (LTCC) technology. The proposed Tx-Rx diplexer has 5 ports and consists of two lowpass filters, two bandpass filters, and one common matching network, which are fully embedded

Design and Implementation of a Diplexer and a Dual-Band VHF/UHF Antenna for Nanosatellites

IEEE Antennas and Wireless Propagation Letters, 2013
CONSAT1 is a nanosatellite of the form 3U CubeSat designed and built by the Space Concordia group at Concordia University during the first Canadian Satellite Design Challenge (CSDC). Its mission is to detect and study high-energy particles in low earth orbits. This CubeSat relies on a single antenna to communicate with a ground station.

Miniaturized Single-Ended and Balanced Dual-Band Diplexers Using Dielectric Resonators

IEEE Transactions on Microwave Theory and Techniques, 2020
Compact dual-band diplexers with single-ended and balanced ports based on quad-mode dielectric resonators (DRs) are proposed in this article. Two pairs of orthogonal degenerate modes are employed not only to form four frequency channels but also to achieve high isolation of dual-band diplexer.

Low Phase Noise Concurrent Dual-Band Oscillator Using Compact Diplexer

IEEE Microwave and Wireless Components Letters, 2015
A novel C-band concurrent dual-band oscillator is presented in this paper. Two diplexers are cascaded back-to-back to realize two loop sub-oscillators. The phase noise of the oscillator is reduced significantly by using the cascaded high-Q diplexers as the frequency stabilization elements.

Compact Dual-Band Diplexer Based on Dual-Layer Substrate Integrated Waveguide

2019 IEEE MTT-S International Microwave Biomedical Conference (IMBioC), 2019
This letter presents a dual-layered diplexer with dual band using a type of strip-line to CPW coplanar transition structure. An example with two channel and each channel of two single-mode $(TE_{101})$ is demonstrated using substrate integrated waveguide technology.

Balanced dual-band diplexer design using microstrip and slot-line resonators

2015 Asia-Pacific Microwave Conference (APMC), 2015
A balanced dual-band diplexer formed using hybrid microstrip and slot-line structure is proposed with good common-mode (CM) suppression in this paper. The balanced dual-band diplexer was constructed by combining two dual-band bandpass filters (BPFs) operating at 1.92/5.25 GHz and 2.45/5.8 GHz, respectively, through T-junctions.

Integrated Antennas and Diplexers for Dual-Band Wireless Local Area Network (WLAN) System

2005 Asia-Pacific Microwave Conference Proceedings, 2006
An integrated design of antennas and diplexers for dual-band wireless local area network (WLAN) systems for the purpose of reducing the component count is reported in this paper. Two antenna structures are used in this design. One is the sleeve monopole antenna, and the other is a novel tapered bent folded monopole.
