1. A method of constructing a dipole antenna, comprising the steps of:
providing an upper mold half and a lower mold half having mating surfaces that mate together to form cavities to receive a feedline, radiating portion, and ceramic portions therein, each of the upper and lower mold halves includes first and second slots, respectively, to receive a polyimide material; placing the feedline into the respective cavity, the feedline including an inner conductor, an outer conductor and an inner insulator disposed therebetween; placing the radiating portion into the respective cavity, the radiating portion including an unbalanced dipole antenna having a proximal portion and a distal portion of different lengths, wherein the proximal portion includes at least a portion of the inner conductor and the inner insulator and the distal portion includes a conductive member; placing the ceramic portions into the respective cavity; mating the upper mold half and the lower mold half together; and depositing the polyimide material into each of the first slots through the second slots and upon cooling, the polyimide material adheres to the distal and ceramic portions to the proximal portion.
