L and S Beacon Dualband Antenna for Biomedical Application

In this work, a beacon antenna was initially created to cover S band (2–4 GHz) and L band (1–2 GHz) for medical purpose, and the proposed antenna covers dual band. From the beacon antenna ground plane developed to increase the gain, directivity, and efficiency. The antenna covers frequency range of S band and L band with low return loss and high gain. In this 2.1 GHz (−38 dB) bandwidth resonated frequency of S band at 1.3 GHz (−28 dB) which is for L band application. Based on this bandwidth data rate can be enhanced to achieve the through port and latency. One such antenna consists of a low, light-weight, as well as low-profile antennas capable of sustaining excellent result more than a wide range of frequencies. ADS was used to produce these antenna simulations. The numerical simulations are shown in elements of percussive frequency reflection coefficient, voltage standing wave, radiation efficiency, receiver sensitivity, and beam width. The application is biomedical, satellite navigation, digital audio and video broadcasting, and weather surveillance radar for air traffic control.
