i have simulated the dipole antena with the vertical position,and it has 2.9 m long,,,with the coil about 47 uH..but the weak point of this antenna is the efficiency of radiation (measured about 4% according tu the 4nec2 simulator)..is it possible to raise up its efficiency?with dimension about...
the magnetic loop antenna have two type,,the transmitting and the receiving,,is it possible to get the antenna performance as good as when it transmit and when it is receive the signal?
is it any reference to build the small two element quad loop antenna?
so,,is there any example of the design with the simulation?thx

how to get the better efficiency at my center frequency when it is receive or transmit?
how about its efficiency?how to boost its efficiency at my center frequency(6.363)...consider that it uses the variable capasitor..
thx

is there any link about complete magnetics loop antenna..from its radiation...
thanks for the recommendation,,,about the magnetic loop..how to wider the direction of the antenna?is there any link that show the radiation pattern of the antenna?or the simulation with NEC or HFSS??
thx:-D
dear all..
i wanna build an antenna at frequency 6.363 MHz (maritime HF frequency),,,it will be the seashore station for traditional fisherman communication,,
i wanna build the directional antenna that can cover the wide-seashore and have less back lobe,,the problem is how to make antenna with...
