Design and Implementation a Non-uniform Helical Antenna in Frequency Range of 450–850 MHz for Ultra-high-frequency Television Application
Abstract
In a domestic region, the people are living inside cities, they complaining from the weak of local TV broadcasting signals in frequency range of 450–850 MHz, in this paper try to get a solution by increase the gain antenna by design new antenna have a wideband and high gain compare with antennas are available in the local market. A non-uniform helical antenna designed using helical antenna calculator according to equations then implemented and measured the radiation pattern and gain of antenna, then compare with commercial loop antenna gain found increase in received power about 10–12 dB more than loop antenna gain. The results of measurement applied in Matlab program to draw the pattern of the antenna.
