    Antenna radiation pattern in hfss

    I do not know how to plot E and H plane radiation pattern separately in hfssv11..... I have searched internet and found that (In proj. manager->radiation->farfield->infinite sphere-> vary phi from 0 to 90 deg, stepsize 90 and vary theta from 0 to 360 deg. step size 3 to 10. Second Step...

    Microstrip patch antenna

    my microstrip antenna is as shown.. plz suggest me ..what should be the boundary conditions to be assign to the patches on lower and upper side and substrate (what to assign radiation,what to assign perfect E or H) ?? (substrate is FR4-epoxy)

    oscillator used in fm radio

    can you tell me what should be the modifications in the circuit below ,to get more radio stations, as i am getting only 1 station which is also full of noise ? Is it would be helpful of applying this oscillator circuit (below )in above circuit ?if yes then plz tell me which terminals should be...

    Confusion about variable capacitor

    i am unable to use the variable capacitor in my circuits,i.e, which pin of variable capacitor should be connected to which point in circuit?

    i am confused about the ganged capacitor pinout

    there are two pins at centre of capacitor ,,so how they are connected to the common connection between C3A and C3B.... "i think that first we have to join both centre pins and then connected to the common connection between C3A and C3B" is my answer right??
