Abstract:
1. A microstrip antenna having an embedded spiral inductor, comprising: an antenna element, including a first dielectric substrate made of a dielectric material with its surface covered with a first wiring pattern, which is an electric circuit, such that the operation of the antenna element is receiving specific signals, transmitting specific signals, or receiving and transmitting specific signals; and a feed-in/feed-out element, operated in conjunction with the antenna element, and provided with the characteristics of outputting specific signals to the antenna element for transmitting, inputting specific signals received by the antenna element, or outputting specific signals to the antenna element for transmitting and inputting specific signals received by the antenna element; wherein, the first wiring pattern includes a first antenna portion, a second antenna portion, and a plurality of spiral inductors; the spiral inductors are disposed between the first antenna portion and the second antenna portion; a first vertical connector is connected to the end of the first antenna portion, which is toward one spiral inductor, and passes through the first dielectric substrate; a second vertical connector is connected to one end of the spiral inductor, which is toward the first antenna portion, and passes through the first dielectric substrate; a horizontal connector arranged on the bottom surface of the first dielectric substrate, connects the first vertical connector and the second vertical connector.
