Are spiral inductors antennas?

I have to choose a topic for a project in my antennas class. We need to simulate an antenna so I chose spiral antennas but I just found tutorials for spiral inductors, they look the same to me, and as I am just a beginner I was wondering if someone could tell me what is the difference. And some papers or HFSS tutorials or anything relating the topic would help too.
thanks!

For low frequency RFID, the "antenna" tags are indeed inductors. They work with inductive near field coupling, which is different from normal far field antenna radiation.

Spiral antennas are different than spiral inductors (in application anyhow :) ) Spiral antennas are very wide bandwidth antennas used that have sizes on the order of the wavelength(s) of interest. Spiral inductors, rather, are electrically very small and tend to be used as inductors rather than radiators. However, this too has caveats, as Volker was saying, most power coupling RFID uses 13.56 MHz for the near field coupling and the range is very limited. The reason spiral inductors are used as near field couplers is not that they are not antennas, they are just very electrically small antennas which have horrid gain in the far field due to their sizes.

A wire wound in a spiral pattern will look like an inductor but will act as one when connected at both ends. But here the full wave length or a quarter length of the antenna is wound in a spiral pattern (without any cores) to minimise space. Here the coil is connected only on one side this certainly will act as antenna.

:( OK, so let's say I want to design an spiral antenna at 13.56 MHz that looks like the pct

which is the basic square inductor in the HFSS tutorial, would that work? I notice @pranam77 mentioned I need to connect it just from one end...
thanks!

Spiral antenna can mean different things.

As I mentioned above, there are electrically small (dimensions << wavelength) spirals, which are basically inductors. These are used for inductive near field coupling in RFID at 13 MHz etc. They are connected and calculated like other inductors. See here for a picture.

And there are spirals antennas which are different in layout (two arms, something like a would up dipole) which are not electrically small. These are "real" antennas with decent far field gain.

Small (compared to a wavelength) spiral antennas were used in the past as covert antennas in automobile windows. These were used by undercover police officers and private detectives. Ones that are large compared to a wavelength and with changing radius have been used for decades as broad band antennas in aircraft warning receivers to indicate an approaching rocket that used radar guidance. I have also seen a small spiral used in a medical implant.
