Embodiment Construction
[0012] A preferred embodiment of the present invention is described in detail as follows in conjunction with accompanying drawing: Refer to figure 1 , 2 As shown, the GPS and Bluetooth dual-band microstrip antenna consists of a radiation patch 1, a dielectric plate 2, a feed point 3, three short-circuit pins 4, 5, 6 and a ground plate 8. An E-shaped slot 7 is opened on the radiation patch 1 to make the antenna exhibit a dual-frequency effect. The dielectric plate 2 adopts a low dielectric constant, and three short-circuit pins 4, 5, and 6 are inserted in the dielectric plate 2 to make the radiation patch The sheet 1 is connected to the ground plate 8, and the resonant frequency can be adjusted by changing the positions of the short-circuit pins 4, 5, and 6. There is only one feeding point 3 , so that it is located on the transverse axis of symmetry of the rectangular radiating patch 1 . The unified modeling and simulation of the above-mentioned models is carried out, and the...
