  1. hello im curently doing my project on helical antenna designed in cavity for 2.4GHz. i had already started designing it with 40
    diameter cavity around a helix but i am not getting satisfactory results.i also visited sites which give helix calculators but its nt working as in a cavity the helix behaves differently. i wanted the helix and cavity parameters. if u want ill also send u the details and pictures of my designs i made in HFSS.
    (i also refered to helical resonators as those are also in cavity only difference is that its closed from the top)
