23 cm antennas are rather small in dimension, and require special SWR meters to tune.

You'll be well served to buy one or two commercial antennas to start with and gain experience with 23 cm before advancing to making and experimenting with home-brew antennas.

See:

Actually, a fairly non-critical, high-gain (directive) antenna design for 23cm, and one which can be built with ordinary household materials, is the Quagi.

Complete details for 23cm (and 144-220-432 MHz) Quagi construction can be found in all the old ARRL VHF Manuals, ARRL Handbooks (from the late 1970's and early 1980's), and also at the designer's website:

A corner reflector is an easy way to get 10dB or so of gain over
a dipole over a wide bandwidth.  Check www.cebik.com.
