Default Antenna design for School Project

Hello all,

We are working on a school project in which we were tasked to design an FM receiver antenna that receives signals at frequencies between 900 Mhz and 1000 Mhz. What are some potential antenna builds/dimensions we should research? Where should we start?

Thanks in advance,

Sean & Raven

AARL has an antenna design book that should help.

It is odd that the modulation mode "FM" is mentioned for this task. Antennas don't normally care what modulation is being used. Is this going to be for a specific application like a TV down-link from a drone? If so, you might want to concentrate on directional antennas with some gain, like a yagi, a helical or patch. Otherwise an antenna can be as simple as a 1/4 wave dipole.

Also the FM between 900 MHz and 1000 MHz. Are you sure the decimal point isn't off one digit?

Do you know what the instructor is looking for in the final design? Will they give more points for gain or band width or small size or ?? With so many types of antennas to choose from in that frequency range it would be nice to know where to concentrate your research.

Knowing what the antenna will be mounted on, and any environmental exposures, would be good.

You can easily build a bowtie antenna from coat hangars and a broom stick

A 4 bay bowtie design is both easy to build and will provide excellent performance
