turnstile antenna

I want to simulate turnstile antenna's field in matlab. Pls guide me for an early result.

Thx & GIG,

If you ever simulate a simple dipole things are not complicated because turnstile antenna consists of two dipoles at 90-degree angles to each other. First dipole is connected to the main feed line, and between the feed point of the first and the second dipole is a 90-degree (1/4 wavelength section coax cable) to obtain the required phase shift between the two dipoles.

Thanx, but my problem is that to simulate in Matlab and for that I dont have any knowledge how to formulate the radiation pattern using two 90 deg crossed dipoles. Also I want to simulate the polarization of the antenna as well. Pl help me 4 above.

there is a book i think it is useful for u
