Logo based dipole antenna for RFID applications

Abstract

Antenna plays an important role in communicating signals between device. With the recent advancement in the IoT and miniaturization of devices, the application of antenna have increased. Wearable electronics have often found device integrated with fabric, providing various electronics functionalities for energy harvesting, medical, defense and consumer electronics. The advantage of the wearable device is, being the part of the fabric it keeps the user connected to various surrounding devices with ease. A logo dipole antenna has been designed here at 865 MHz for RFID applications. The antenna has been designed for its integration with various RFID chips. Various antenna parameters such as return loss, gain directivity, bandwidth and efficiency has been calculated and analyzed.
