A miniaturized microstrip antenna with variable broadband operation comprised of a ground patch, an isosceles-triangular patch with a base side, two isosceles sides, a top angle opposite the base side and two base angles. A pair of primary slots extending from the top angle sides toward the base angles are embedded in the isosceles-triangular patch. At least one pair of secondary slots extended from each primary slot. A substrate is located between the ground patch and the isosceles-triangular patch. The primary slots are approximately parallel to the sides of the isosceles-triangular patch. The second and the third slots branching from the primary slots are approximately perpendicular to the base side of the isosceles-triangular shaped patch. It is found that by selecting a proper dimension, the good broadband operation can be obtained. Lastly, inclusion of the slots and adjustment of the size of the slots on the microstrip antenna allows for a reduction in overall size and area of the microstrip antenna.
