–

W – width

L – length

Rectangular substrate is assumed

Discrete port

View full size image

Px.r – horizontal position

Py.r – vertical position

Px = Px.rW/2

Py = Py.rL/2

Port position is determined relative to the substrate center

Ground plane

Lg.r – ground plane length

Lg = Lg.rL/2

Ground plane length is relative to the substrate length

Elliptic patch

View full size image

Sx.i.r – horizontal position of ith patch

Sx.i.r – vercical position of ith patch

ax.i.r – horizontal axis of ith patch

ay.i.r – vertical axis of ith patch

Sx.i = Sx.i.rW/2

Sy.i = Sy.i.rL/2

ax.i = ax.i.rW/2

ay.i = ay.i.rL/2

Patch size is relative to the substrate size

Elliptic gap

Rx.i.r – horizontal position of ith gap

Rx.i.r – vercical position of ith gap

bx.i.r – horizontal axis of ith gap

by.i.r – vertical axis of ith gap

Rx.i = Rx.i.rW/2

Ry.i = Ry.i.rL/2

bx.i = bx.i.rW/2

by.i = by.i.rL/2

Gap size is relative to the substrate size
