NEC-LIST: Patch linear phased antenna array

Hi all

  The specification given below are for a microstrip patch linear phased
antenna array.
  If one ask you to explain each specification how will you go about
doing that?

  I am trying to come up with an idea of achieving a particular squint
(as stated below 30
  degrees from the broadside direction) with only four patches, is that
feasible or attainable?

  Is the topic suitable? i.e. should the particular antenna be called
the Linear phased antenna array?

Specifications

  ? Operating frequency 2.37 GHz
  ? Input impedance 50 ohm
  ? Polarisation Linear
  ? Gain 9 dBi
  ? Return loss < -15 dB
  ? Bandwidth 1%
  ? Beamwidth 25 degrees in the H-plane
  ? Squint angle 30 degrees
  ? Side lobe level < -10 dB

  Any help in this regard will be optimally appreciated.

  Thank you.
  Samson
