Method for constructing a dipole antenna
View Patent ↗A method of constructing a dipole antenna assembly is disclosed. The method includes providing a pair of mold halves and placing a feedline and a radiating portion within a cavity formed by the pair of mold halves, the radiating portion including a proximal portion and a distal portion separated from the proximal portion. The method further includes mating the pair of mold halves together to house the feedline and radiating portion within the cavity. A polyimide material may be injected through at least one inflow slot disposed through the mold halves into the cavity to adhere the distal portion to the proximal portion.
1. A method of constructing a dipole antenna, comprising:
providing a pair of mold halves;
placing a feedline and a radiating portion within a cavity formed by the pair of mold halves, the radiating portion including a proximal portion and a distal portion separated from the proximal portion;
mating the pair of mold halves together to house the feedline and radiating portion within the cavity; and
injecting a polyimide material through at least one inflow slot disposed through the mold halves into the cavity to adhere the distal portion to the proximal portion.
2. The method according to claim 1 , wherein the proximal portion has a different length than the distal portion.
3. The method according to claim 1 , further including injecting the polyimide material through the at least one inflow slot until the polyimide fills at least one outflow slot disposed through the mold halves.
4. The method according to claim 1 , further including placing a distal tip within the cavity prior to mating the pair of mold halves together.
5. The method according to claim 4 , wherein injecting the polyimide material through the at least one inflow slot adheres the distal tip to a distal end of the distal portion.
6. The method according to claim 1 , further including placing a ceramic layer within the cavity prior to mating the pair of mold halves together.
7. The method according to claim 6 , wherein injecting the polyimide material through the at least one inflow slot adheres the distal portion and the ceramic layer to the proximal portion.
8. The method according to claim 1 , wherein the feedline includes an inner conductor, an outer conductor, and an insulator disposed therebetween.
9. The method according to claim 8 , wherein at least a portion of the inner conductor and the insulator are disposed within the distal portion.
10. The method according to claim 1 , further comprising heating the polyimide material prior to injecting the polyimide material through the at least one inflow slot.
11. The method according to claim 10 , wherein the polyimide material adheres the distal portion to the proximal portion upon cooling.
12. A method of constructing a dipole antenna, comprising:
providing a pair of mold halves;
placing a feedline and a radiating portion within a cavity formed by the pair of mold halves, the radiating portion including an unbalanced dipole antenna having a proximal portion and a distal portion separated from the proximal portion, the feedline including an inner conductor, an outer conductor, and an insulator disposed therebetween;
mating the pair of mold halves together to house the feedline and radiating portion within the cavity; and
injecting a polyimide material through at least one inflow slot disposed through the mold halves into the cavity to adhere the distal portion to the proximal portion.
13. The method according to claim 12 , wherein the proximal portion has a different length than the distal portion.
14. The method according to claim 12 , wherein at least a portion of the inner conductor and the insulator are disposed within the distal portion.
