This paper presents coplanar waveguide (CPW) fed slot antenna. A rectangular slot antenna is excited by a 50 ohm CPW with L-shaped tuning stub. It can achieves wide band from 2.0 GHz to 6 GHz which is the frequency band covered the standard IEEE 802.11a/b/g for use in WLAN (Wireless Local Area Network) and covered the WiMAX (Worldwide Interoperability for Microwave Access, 2-6 GHz). The charact...

The fractal antennas that have the multiband operation due to the self-similar property in fractal geometry, which plays a key role to create a fractal circular monopole patch antenna. The other important property that is, Space-filling property which actually determines the reduction in the size of the antenna. This property adds more electrical length in less volume which reduces the size of ...

Background: Transcutaneous electrical nerve stimulation (TENS) is a noninvasive, inexpensive and safe analgesic technique used for relieving acute and chronic pain. However, despite all these advantages, there has been very little research into the therapeutic effects of TENS on brain activity. To the best of our knowledge, there is no evidence on the effect of high frequency TENS on the gamma ...

This paper presents a new design of dual band RFID reader antenna for ISM-band industrial science and medical applications at 2.4 GHz 5.8 GHz. Theantenna is designed physically built using FR4 substrate taking 1.5 thickness, 4.3 relative permittivity 0.025 loss tangents. Different slots havebeen introduced to reduce the dimensions achieve bandfor microwave ISM application. The dimension propose...
