A coplanar waveguide (CPW) fed rectangular loop antenna with dual frequency characteristics applicable Wi-Fi bands is presented. The studies to calculate the dependency of frequencies on the antenna structure is carried out using ANSYS HFSS. From this, the antenna is optimized to have an enhanced gain of ~ 8 dBi at 2.45 GHz and 3.83 dBi at 5.32 GHz. The radiation characteristics of the antenna are studied and the radiation pattern confirms the monopole characteristics at both the frequencies. The optimized antenna performance is confirmed by measurements using Vector Network Analyser. Since energized using coplanar waveguide the proposed antenna finds applications in Microwave Monolithic Integrated Circuits (MMIC) also.

An antenna is an integral component in a wireless communication system. The choice of the antenna geometry of these systems depends on the preferred specifications. Depending upon the variation in the geometry and feeding technique, the performance of the antenna can be modified. For any communication system design an antenna with a better transmission range, improved reflection and radiation characteristics at the designed frequencies is desired. An asymmetric coplanar strip fed antenna is designed and analyzed in this paper. This structure gives better performance compared to microstrip and coplanar waveguide (CPW) fed omni-directional antennas. The proposed antenna is compact with reduced complexity, providing appreciable gain. A monopole antenna system with a metamaterial ground plane on the same plane is proposed. This antenna operates in the 2.45 GHz Wi-Fi band. The radiating element and the metamaterial ground plane are optimized for the best performance of the antenna system. For optimum performance of the antenna, open loop resonator is also studied as the ground plane. Miniaturization is achieved with metamaterial ground plane without changing the characteristic of the monopole antenna structure. The monopole antenna with the metamaterial ground plane is found to be compact with resonance at 2.45 GHz offering a 2 : 1 VSWR bandwidth of 217 MHz. The radiation pattern of the designed antenna is omni-directional with a gain of 3.124 dBi at the resonant frequency. The antenna is designed and optimized using ANSYS HFSS 14. The optimized antennas are fabricated using FR4 substrate and are experimentally validated using Vector Network Analyzer E5080A.

For efficient monitoring and tracking of vehicles, aircraft or ships GPS (Global Positioning System) satellite based navigation system plays an inevitable role. For long range GPS communication and tracking, high gain antennas usually array antennas are preferred. Realized using butler matrix phased array antennas are potential candidate for providing long range communication providing directional beam. Butler matrix provides equal amplitude to the antennas by means of hybrid coupler, necessary beam orientation using phase shifter and ensures signal purity when transmission lines overlap by crossover circuit. Thus crossover will mitigate the GPS tracking of signal when transmission lines overlap each other maintaining high SNR. This paper focuses on the investigations of an L band planar crossover realised using microstrip technology. The crossover characteristics like transmission and isolation are analysed in detail. For enhancing the isolation between the decoupled ports, parent crossover is further modified maintaining good transmission between coupled ports. The analysis is done using ANSYS HFSS and the optimised crossover is fabricated on FR4 substrate and measurements are taken by using Keysight ENA 5080A Vector Network Analyser. The simulated and measured results are in good agreement with each other. This proposed crossover is the possible solution for long range wireless communication and GPS Applications.

Betsy George, Bhuvana, N. S., and Dr. Sreedevi K Menon, “Design of edge coupled open loop metamaterial filters”, in 2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), St. Petersburg, Russia, 2018.[Abstract]


Metamaterials with negative index of refraction has created great opportunities for novel applications at Radio Frequency. Metamaterial finds applications as filters, diplexers and as frequency selective surfaces for gain enhancement in antennas. In this work open loop filters with circle, triangle and pentagonal geometries are proposed which can be configured as metamaterial for various wireless applications. These metamaterials can be energised using different feeding mechanisms like edge coupling, electromagnetic coupling, inductive coupling, capacitive coupling etc. Proposed filters are energised using edge coupled feeding mechanism which has reduce complexity compared to other techniques. Edge coupling also ensures the tunability of the filters and make them applicable for low frequency, where the conventional planar filters consumes large area. The geometrical variations in the loop are found to influence the filter characteristics and this is studied in detail. Design equations are furnished for the filters based on the extensive analysis carried out using ANSYS High Frequency Structure Simulator (HFSS) using finite element method. The current distribution and electric field of the proposed filters are also analysed in detail. Filter prototypes with optimum performance as seen in the simulations are fabricated and measured using Keysight ENA 5080A Network Analyser. Good agreement is found to exist between experimental results and the simulated results for the designed filters. A comparative study is carried out based on the frequency of operation, bandwidth and the attenuation of the three designed filters among themselves and the previous works that authors referred into.</p>

Betsy George, Bhuvana, N. S., and Dr. Sreedevi K Menon, “Compact band pass filter using triangular open loop resonator”, in 2017 Progress in Electromagnetics Research Symposium - Fall (PIERS - FALL), Singapore, Singapore, 2018.[Abstract]


Recent developments in wireless communication challenges microwave filters with more demanding requirements such as small size, light weight, high performance and low cost. Microstrip resonator have the higher performance than the conventional filtering technique for microwave devices. A triangular open loop resonator energized using electromagnetic (EM) and edge coupling is presented in this paper. Microstrip line is modified as a triangular open-loop resonator that introduces additional capacitance and inductance by re-orientation of electromagnetic field, there by selecting the operating frequencies. Depending on the type of coupling and position of the feed used the operating frequency of the filter changed for the same dimensions. EM and edge coupling is given to the resonator, when its gives band pass filters at 2.45 GHz and the effect of each coupling techniques are studied in detail. Better size reduction is observed for EM coupling than the edge coupling. The filters characteristics are analyzed in substrate FR4 epoxy by using ANSYS High Frequency Structure Simulator (HFSS) software. The design equations for the resonator predicts the frequency with less than 2% error with the simulated frequency. The optimized triangular open loop resonators are fabricated and validated using Keysight ENA 5080A Vector network Analyser. The simulated and measured of the resonator filter are comparable for center frequency, bandwidth, return loss and attenuation.
