Hi, Does anyone knows any companies specializing
in designing very small broadband VHF antennas (couple
of cm) with gains higher than -20 dBi, Omni pattern
and matched over a band of 169 to 218 MHz (VSWR
2:1)? Any help is appreciated. Thanks
SS

Hi sos, A book named Small Antennas may
be helpful for your design. It was written by K.
Fujumoto and published by Reserach Studies Press
in 1988. You may look it from the library.

Hi Feng, Thanks for your reply. I will look
into that book for design ideas, but I wanted to
check if there was anything aleady available. Please
let me know if you are aware of any companies making
these type of antennas. Thanks

Hi sos, There is the company dedicates to
small antennas and its website is
https://www.antenova.com/. However, there isn't
an antenna in the band you required. I think this
kind of antenna, which has special requirements,
may need to custom design. By the way, its
omni pattern is at all directions or just in a plane?
There is a big difference between them.
