why i have different answers ? half wave dipole antenna
i have used three programs in order to get gain and impedance (MANAMA,PCAAD,EXNEC) i have give the same parameters but each program give me different answers why i cant understand as i know these programs uses the same method (MoM) and i...
why i have different answers
i have used three programs in order to get gain and impedance (MANAMA,PCAAD,4NEC2) i have give the same parameters but each program give me different answers why i cant understand as i know these programs uses the same method (MoM) and i want to ask how does MoM...
reactance -,+
thanks but so u mean i have aproblem just in matching the impedance ....how could u find these valuses ....does the negative value effect on the performance of antenna
reactance -,+
dear friends its nice to see ur answers but im not that good in these calculations and i dont have that much good back ground ....i just want to know is it good answer or bad (can it be used in practical life ) and what about nagetative value how does it efect...... im sending my work
i have designed yagi uda antenna considering a channel works on frequcey 199.25 mhz chanel 11 in north cyprus... using 4nec2x and get these results number of elements 5 and the gain is 9.7 and input impedance was 44.5-j32.03 and effecency was 96.88% so according to theoritical part i think i got...

reactance -,+
thanks for the answers but dear shg could you plz cheack your answerto make sure coz u have written that Positive value of reactance means is too long and a gain you have writtern positive reactance means that antenna is too short so could u plz correct it for me again thanks for...
i have simulated the dipole antenna with different lengths and when i find the input impedance i find that i have some positive values for reactance and some negative values why i got these answers and how does reactance effect on performance of antenna
