```Here's one way, albeit using the PolarDraw function from David Park's
"Presentations" package:

Needs["Presentations`Master`"]

Draw2D[{
(* Draw the polar curve *)
Directive[Thick,Brown],
PolarDraw[Cos[5\[Theta]],{\[Theta],0,2\[Pi]}],
(* Draw the polar grid *)
Directive[Thin,Legacy@DimGray],
ComplexCircle[0,#/8]&/@Range[8],
ComplexLine[{0,ComplexPolar[1,# Pi/6]}]&/@Range[0,12]
},
Background->LightBlue]
