Abstract
In this paper, a novel approach to downsize the length of a dipole antenna has been stated. The dipole antenna is widely used in Radio and TV reception, Radar altimeter, etc. As dipole antennas are used inside home in TV and Radio sets the length of the dipole antenna causes inconvenience. We know the resonant frequency (f) and the wavelength (λ) of an antenna are inversely proportional to each other. So lower the frequency, higher the length of the antenna as dipole antenna length is directly proportional to the wavelength. Here a 100 MHz VHF dipole antenna frequency has been left shifted to 75 MHz without increasing the antenna length and without hampering the antenna performance. This is possible by covering the antenna with an RT Duroid 6010 cylindrical case. In other words a 75 MHz antenna length is downsized to the length of a 100 MHz antenna. The antenna has been designed and simulated using HFSS.
