Could an antenna made from a non-conductor or a poor conductor?
What is your background in antennas?qnach said:Could an antenna made from a non-conductor or a poor conductor?

Having asked that, I have looked a bit into ways to try to make a hybrid optical/EM antenna, but am still working on that.
What is your application?
qnach said:to receive solar energy
Yes. A dielectric lens could be used to focus EM energy onto a semiconductor mixer or ferrite rotator.qnach said:Could an antenna made from a non-conductor or a poor conductor?

You do need to be much more specific with your question if you actually want a useful answer.
ZapperZ said:You really should get into the habit of posting a more elaborate question, especially with a bit of reasoning thrown into describe why you are seeking such a thing.
For example:
1. If all you want is to "receive solar energy", why are you opting for an antenna?
2. If all you want is to "receive solar energy", why does the antenna need to be a "a non-conductor or a poor conductor"?
3. What exactly is this "solar energy" that you want? It is a rather broad EM spectrum. Are you hoping to collect ALL of it, even the UV and IR?
Zz.
Search on Rectenna...qnach said:Solar energy is a kind of EM waves...so I am using antenna to receive it!
Not until you identify the wavelength range of the proposed antenna, and explain what you are really trying to do.qnach said:Could you be more elaborate or give some examples, or URL?
about 800 nm to receive sun lightBaluncore said:Not until you identify the wavelength range of the proposed antenna, and explain what you are really trying to do.
Did you do the search I asked for?qnach said:about 800 nm to receive sun light
it is not on the topic I asked.berkeman said:Did you do the search I asked for?
The less you specify your goals, the broader the answers.qnach said:it is not on the topic I asked.
And this one is on topic. The more as you didn't answer:Baluncore said:You do need to be much more specific with your question if you actually want a useful answer.

what is that? You told me there are lens? antenna? mixer? ferrite rotator?Baluncore said:For 800 nm, look for a molecule that can be activated by a photon with an energy of 1.55 eV.
That was before you released the critical wavelength information.qnach said:You told me there are lens? antenna? mixer? ferrite rotator?
Microwave frequencies.qnach said:What kind of frequency do they use?
tell me more on microwave region...Baluncore said:That was before you released the critical wavelength information.
Microwave frequencies.

What do you want to do with the energy, that cannot be done with a common photovoltaic panel ("solar panel")?qnach said:to receive solar energy
It is definitely on-topic if you are wanting to receive light energy with antennas.qnach said:it is not on the topic I asked.
Baluncore said:A metal half-wave dipole antenna would only be 400 nm long so it would have a capture area of about 10-12 m2.
You need an array of molecules like an algal-film or a leaf.
You would cook a non-metalic antenna in sunlight if you used a parabolic reflector or a lens.

Please be much more specific about what you are asking, or this thread will be closed. You are wasting our time with your obtuse and changing questions...
Thread is locked until @qnach sends me a PM explaining in detail what they are asking about.qnach said:O.K. let's switch to 1 cm wave.
A non-conductor made antenna is an antenna that is made from materials that do not conduct electricity, such as plastic, wood, or ceramic. This type of antenna is used in situations where metal antennas may interfere with the surrounding environment or cause safety hazards.
Like all antennas, a non-conductor made antenna works by converting electrical energy into electromagnetic waves, which can then be transmitted or received. The non-conductive material used in the antenna does not affect this process, but it is designed to reduce interference and provide a safer alternative to metal antennas.
The main benefit of using a non-conductor made antenna is its ability to reduce interference with the surrounding environment. This is particularly useful in sensitive areas such as hospitals, airports, and military installations. Non-conductive antennas are also safer to use in situations where there is a risk of electrical shocks or arcing.
One limitation of non-conductor made antennas is their lower conductivity compared to metal antennas. This can result in a decrease in the antenna's efficiency and range. Additionally, non-conductive materials may not be suitable for use in all weather conditions, so the antenna's performance may be affected in extreme temperatures or humidity.
When choosing a non-conductor made antenna, it is important to consider the specific requirements of your application. Factors such as the frequency range, power handling capabilities, and weather resistance should be taken into account. It is also important to select an antenna from a reputable manufacturer to ensure quality and performance.
