microstrip circuits can radiate
microstrip line is unbalanced line so it works in same way as other unbalanced line. so in double stub, the microstrip line forms the reactance wanted to match. Hey what happened to methods involving the schmidt chart?

The source of radiation for rectangular microstrip radiator is the electric field that is excited between the edges of microstrip element and the ground plane.The fields are excited 180 degree out of phase between opposite edges.Each edge therefore radiates an omnidirectional pattern into half space above the ground plane.The opposing edges are excited out of phase but their radiation adds in phase normal to the element. For more details see Antenna Engineering handbook by Johnson and Jasik. Thanks.
microstip patch array antenna is basically ,thecollection of antenna that give the double directive gain

A micro-strip antenna works on the principle of resonant cavity (short circuit walls on top and bottom, open circuit walls on the sides).A resonant cavity stores energy unlike transmission lines or wave guide which transmits electromagnetic energy from one part to another. A R.C is equivalent to LC device at low frequencies.
