1. A three-dimensional antenna structure, which is applicable to a transmission frequency band, the three-dimensional antenna structure comprising:
an insulating carrier including a first substrate and a second substrate that are spaced apart from each other;
an M number of first antennas disposed on one of two side surfaces of the first substrate, wherein the M first antennas are spaced apart from each other, and M is a positive integer greater than or equal to 3;
an M number of microstrip lines respectively and electrically coupled to the M first antennas, wherein each of the M microstrip lines has a grounding point and a connection point;
a second antenna disposed on one of two side surfaces of the second substrate, wherein the second antenna is electrically coupled to the M first antennas through the connection point of each of the M microstrip lines, the second antenna has an M−1 number of line segments, and any end of each of the M−1 line segments correspond in position to one of the connection points, and wherein a length of each of the M−1 line segments is 1/M times a wavelength corresponding to a center frequency of the transmission frequency band; and
a grounding element disposed on another one of the two side surfaces of the second substrate, wherein the grounding element is electrically coupled to the M first antennas through the grounding points of the M microstrip lines.
