1. An antenna system in an electronic device, the antenna system comprising:
a first antenna configured to operate at a first frequency band, wherein the first antenna comprises a plurality of openings; and
a second antenna configured to operate at a second frequency band, wherein a feeding network of the second antenna is embedded within a transmission line medium of a signal return path of the first antenna such that the transmission line medium comprises the feeding network of the second antenna,
wherein the second antenna comprises an array of antenna elements, at least one antenna element of the array of antenna elements is inside one of the plurality of openings of the first antenna and configured to radiate through the one of the plurality of openings of the first antenna,
wherein the electronic device comprises a first printed circuit board (PCB) comprising a processor and a modem, and wherein the second antenna further comprises:
a flex circuit;
a circuit clip (c-clip);
a second PCB electrically coupled to the first PCB using the c-clip or a flex circuit board electrically coupled to the first PCB using the c-clip; and
an integrated circuit (IC) mounted on the second PCB or on the flex circuit board, the IC configured to electrically couple to the array of antenna elements of the second antenna using the flex circuit.
