Receiver antenna selection

Hello there,

I am presently trying to select what antenna to purchase for this project I am working on. I am trying to receive 2.4 GHz signals from an access point in my university. Its a Cisco 3600 Series AP operating at dual frequencies (2.4 GHz and 5 GHz) (I am only interested in the 2.4 GHz). Its max transmit power is 23 dBm and the integrated 2.4 GHz antenna has 2 dBi gain.
Also, it is omni directional.

Based on this information, I am trying to decide what receiver antenna to purchase for my circuit. I know the following:
1) I need an omni-directional antenna
2) length of receiver antenna has to be 1/2 of the wavelength of RF signals I am receiving, so for a 2.4 GHz signal, length of my antenna should be 6.25 cm.

I need assistance in deciding the following:
1) the gain of the antenna
2) the type of antenna (yagi, whip, dipole, etc)

Your suggestions and why?

Regards

Pheezy

Thank you for your reply.

It clarifies what type of antenna I should I be going for (omni-directional was what I was thinking). But how do I know what gain of receiver antenna I should be going for?

Does the receiver gain have to be the same as the transmitter antenna gain?

Regards
