Embodiment
Followingly describe technology contents of the present invention, structural feature, the purpose that realizes and effect in detail with reference to embodiment and conjunction with figs..
See also Fig. 1, the utility model antenna assembly 100 is provided with housing 1, mobile phone communications antenna 2, global positioning system antenna 3 and radio broadcasting reception antenna 4.Housing 1 roughly becomes triangular pyramidal, is provided with the base 10 and lid 11 that combine, and lid 11 is provided with interconnective the first side wall 12, second sidewall 13 and the 3rd sidewall 14.Base 10 is forming an angle portion 15 with respect to the 3rd sidewall 14 places.
Mobile phone communications antenna 2, global positioning system antenna 3 and radio broadcasting reception antenna 4 all are arranged at housing 1 inside.When real enforcement, the strong magnets (not shown) can be set in the bottom of base 10, antenna assembly 100 firmly is adsorbed on the car body, when not using antenna assembly 100, can finish dismounting apace.
Mobile phone communications antenna 2 is arranged on the inner surface of the 3rd sidewall 14 of lid 11.Mobile phone communications antenna 2 is provided with low frequency radiation portion 20 and high-frequency radiation part 21, and the mobile phone communications frequency band than low frequency can be received and dispatched by low frequency radiation portion 20, for example GSM850MHz and EGSM 900MHz.High-frequency radiation part 21 can be received and dispatched the mobile phone communications frequency band of higher-frequency, for example DCS 1800MHz and PCS 1900MHz and WCDMA2100MHz.
Radio broadcasting reception antenna 4 is arranged on the inner surface of the first side wall 12 of lid 11 and second sidewall 13, and is arranged in the middle of mobile phone communications antenna 2 and the global positioning system antenna 3.During real enforcement, radio broadcasting reception antenna 4 can be FM antenna, AM antenna, UHF antenna, VHF antenna, DVB antenna, DAB antenna etc.In the present embodiment, 4 one-tenth strips of radio broadcasting reception antenna, when really implementing, radio broadcasting reception antenna 4 can be antenna component (Chip Antenna).
