ABSTRACT: As the communication tool, implantable devices have been introduced with great interest. By using wireless link, the vital information (such as blood pressure, temperature, thyroid, cardiac beat, sugar level, cancer identification etc.) can be transmitted from implantable devices to external equipment. Therefore, the research on the implantable devices are very popular. When there is a need for information exchange, ISM band (industrial, scientific and medical band) which is ranges from 2.4 - 2.5 GHz is used. In this paper, a microstrip patch antenna design which is combination of spiral and traditional rectangular geometry is designed, simulated and analysed. The proposed antenna design operated at the 2.45 GHz band. The antenna design is excited with the strip line feed method and analysed using different substrate materials (Roger 3010, FR4 epoxy, silicon, alumina). The same antenna design is modified using another feeding method i.e., coaxial feed method. The results of antenna design and modified antenna design are also compare in this paper.
