Planar dual monopoles for contactless low power transfer / Siti Thaqifah Md Zin

A design of two planar dual monopoles combination is presented to study the feasibility in transferring low power signal wirelessly within a very short distance. Two identical sets of dual monopoles having circular form, and placed on top of each other, are used for transmitting and receiving. The operation frequency is chosen to be centered around 2.5 GHz, to ensure small dimensions of the overall circuit. The proposed configuration is designed and simulated using Computer Simulation Technology (CST), and realized using microstrip technology on FR4 substrate of 4.3 dielectric constant, and of 1.6 mm thickness. Vector Network Analyzer (VNA) was used to measure all the parameters of the antenna such as return loss, insertion loss and VSWR.
