Broadband V/UHF Wire Monopole Antenna 30-512 MHz

Faruk_Gungor

Hi,

I am currently working on the design of a broadband V/UHF wire monopole antenna covering the 30–512 MHz frequency range in Altair FEKO. Although I can model a basic wire monopole structure, the antenna exhibits a narrowband response, and I am looking for methods to increase the operational bandwidth.

Could you please advise on recommended approaches within FEKO to achieve broader bandwidth for a wire-type monopole? In particular, I am interested in:

1. Geometry-based bandwidth enhancement techniques
   • Adding top-loading structures
   • Using inductive or capacitive loading
   • Implementing tapered or thickened monopole profiles
   • Employing resistive loading for ultra-wideband performance
2. Lumped element integration in FEKO (voltage sources, series/parallel RLC loading)
   • How to place and optimize lumped components along the wire
   • Typical values or strategies used in wideband V/UHF monopoles
3. Example FEKO models or reference studies
   • Existing FEKO application notes for wideband wire monopoles
   • Recommended tutorial models or technical papers demonstrating similar broadband concepts

If you have any sample FEKO files, publications, or design guidelines specifically related to wideband wire monopole structures, I would greatly appreciate it.

Thank you in advance for your time and support.
Best regards,

Jaehoon

Hello,

I'd like to introduce one Feko book whose title is "Antenna analysis and design using feko electromagnetic simulation software".

Please refer to the chapter 6: Broadband dipole antennas.

Best regards,
