Active Antenna for VHF Band Applications
Journal Title: UNKNOWN - Year 2015, Vol 4, Issue 4
Abstract
This paper gives an idea of designing an active antenna using an active device of field effect transistor (FET).In this active antenna, an active circuit using an active device HEMT is designed with a monopole at its input. The active circuit is mainly used for trans-impedance characteristics. This active antenna can be used to receive VHF band (174-216MHz) frequencies of around 200MHz. Thus a small size antenna having high gain, low noise, large bandwidth can be developed using this technique.
