چکیده مقاله:
In this paper, a new wide band Micro strip antenna for implantable biomedical application in the frequency of ISM (industrial, scientific and medical) band (2.4– 2mm 20× 20 antenna is The total size of the proposed. is presented )GHz 2.48with the thickness of 1 mm , and this antenna is embedded in FR4 substrate with dielectric constant of 4.4. The antenna parameters show good results such as lower return loss, perfect impedance matching, and better gain. The 3-dB axial ratio bandwidth is 2.2GHZ( from 1.2 -3.4 GHz) that is broader than the other conventional antennas. The proposed antenna possesses the return loss of -29 dB at 2.4GHz. Thus the proposed antenna can be employed for several implantable applications.
