150Khz Antenna question

Anyone can help me with the design of a compact 150Khz antenna?

Let me explain the goal, I need a way to induce a 150Khz signal to a 
compound for an experiment.

I will build a supply using a LM555 at 13.8Vdc and a transformer to
produce 
a 150Khz square wave of 140Vp-p approx.

I need to couple that 150Khz signal to a sort of compact antenna to 
emit/induce the wave to the compound. The coil should be compact enough to

be insert in a plastic case of 2" x 4" inches.

What is the best length of wire to use? What is the best way to wound it?

Any suggestions?

Jacques
