However, to ensure the supply of the entire area, high transmission power is required. Another disadvantage is the fact that there is nearly no possibility to adjust the transmitter with respect to the local topography. To mitigate the above mentioned disadvantages, a new broadband antenna structure… CONTINUE READING
