The vpol results of Table 2 are improved by an average of 0.37 dB with respect to those in Table 1.
Rectangular patch arrays may also be designed for two simultaneous feed locations, e.g., hpol feed at A and the vpol feed at B.
In the above equation, [[phi].sub.fhn] and [[phi].sub.fvn] represent the phases of the hpol and vpol feed radiations at the patch n respectively while [[phi].sub.whn] and [[phi].sub.wvn] are the incident hpol and vpol plane wavefront phases at patch n respectively.
The gain values for hpol and vpol feeds at O are similar to those in Table 1.
For an hpol feed at A and a vpol feed at B, we consider an hpol plane wave from ([[theta].sub.hp], [[phi].sub.hp]) incident at a patch in panel number p while a vpol plane wave is also incident from ([[theta].sub.vp], [[phi].sub.vp]).
(9), [[phi].sub.fhnp] and [[phi].sub.fvnp] represent the phases of the hpol and vpol feed radiations at the patch n in panel p respectively while [[phi].sub.whnp] and [[phi].sub.wvnp] are the incident hpol and vpol plane wavefront phases at that patch respectively.
