  • Compact UWB Slotted Monopole Antenna with Diplexer for Simultaneous Microwave Energy Harvesting and Data Communication Applications
    Progress In Electromagnetics Research C, Vol. 109, 169–186, 2021 Compact UWB Slotted Monopole Antenna with Diplexer for Simultaneous Microwave Energy Harvesting and Data Communication Applications Geriki Polaiah*, Krishnamoorthy Kandasamy, and Muralidhar Kulkarni Abstract—This paper proposes a new integration of compact ultra-wideband (UWB) slotted monopole antenna with a diplexer and rectifier for simultaneous energy harvesting and data communication applications. The antenna is composed of four symmetrical circularly slotted patches, a feed line, and a ground plane. A slotline open loop resonator based diplexer is implemented to separate the required signal from the antenna without extra matching circuit. A microwave rectifier based on the voltage doubler topology is designed for RF energy harvesting. The prototypes of the proposed antenna, diplexer, and rectifier are fabricated, measured, and compared with the simulation results. The measurement results show that the fractional impedance bandwidth of proposed UWB antenna reaches 149.7% (2.1 GHz–14.6 GHz); the diplexer minimum insertion losses (|S21|, |S31|) are 1.37 dB and 1.42 dB at passband frequencies; the output isolation (|S23|) is better than 30 dB from 1 GHz to 5 GHz; and the peak RF-DC conversion efficiency of the rectifier is 32.8% at an input power of −5dBm. The overall performance of the antenna with a diplexer and rectifier is also studied, and it is found that the proposed new configuration is suitable for simultaneous microwave energy harvesting and data communication applications. 1. INTRODUCTION Simultaneous wireless power transmission and communication is a promising technology that is intended to transmit power in free-space without wires and also provides data communication.

    Proceedings of the 46th European Microwave Conference Multi-Coupled Resonator Microwave Diplexer with High Isolation Augustine O. Nwajana, Kenneth S. K. Yeo Department of Electrical and Electronic Engineering University of East London London, UK [email protected] Abstract—A microwave diplexer achieved by coupling a dual- and dual-band filter (DBF) design [7], engineers can achieve band bandpass filter onto two single-bands (transmit, Tx and diplexers purely based on existing formulations rather than receive, Rx) bandpass filters is presented. This design eliminates developing complex optimisation algorithm to achieve the the need for employing external junctions in diplexer design, as same function. Also, since the resultant diplexer in this paper is opposed to the conventional design approach which requires formed by coupling a section of the BPF resonators, onto a th separate junctions for energy distribution. A 10-pole (10 order) section of the DBF resonators, a reduced sized diplexer is diplexer has been successfully designed, simulated, fabricated achieved. This is because the energy distributing resonators and measured. The diplexer is composed of 2 poles from the dual- (that is, the two DBF resonators), contribute one resonant pole band filter, 4 poles from the Tx bandpass filter, and the to the diplexer Tx channel and one resonant pole to the diplexer remaining 4 poles from the Rx bandpass filter. The design was implemented using asynchronously tuned microstrip square Rx channel. Therefore, the large size issue with the open-loop resonators. The simulation and measurement results conventional diplexer design can be avoided, as external show that an isolation of 50 dB is achieved between the diplexer junctions (or external/common resonator) are not required.

    ANALYSIS AND SYNTHESIS OF MILLIMETRIC E-PLANE DIPLEXERS IN RECTANGULAR WAVEGUIDE -Antonio Morini, Tullio Rozzi Dipartimento di Elettronica e Automatica, Universitk di Ancona ABSTRACI A novel E-plane diplexer is proposed and discussed. Its feature is the matching section of the three-port junction, obtained by means of an E-plane septum, realized on the same mask as the branching filters and placed in the cavity of an abrupt E- plane junction. The latter is designed-in such-a way that, when combine d with two,reasbnably 7good filters, separately designed and suitably positioned, the resulting diplexer gives good performances without further optimization. This design technique, based on the properties of the scattering parameters of a reciprocal lossless three-portjunction, is , as such, of general validity and easily extended to other structures. INTRQD_UCTION The more expensive part of an E-plane circuit in rectangular waveguide for millimetric application is its housing. In fact, its fabrication requires high precision milling machines and it is difficult to: reduce tolerances below 10 t for each half housing. Therefore, it becomes important to simplify as much as possible the housing geometry, even increasing the complexity of the mask. For this reason, we study an E-plane diplexer based on an abrupt three-portjunction, in lieu of a tapered junction, Dittlof and Andt- (1-2), Vahldieck and Varailhon- de la Filolie(3), requiring more expensive mechanical construction. The junction is tuned by a single inductive post, built on the same mask as the E-plane filters and placed between the junction and the bifurcation, as shown in fig.1, Morini et al.
