ABSTRACT:
A new wide-frequency-band spherical antenna structure which comprises a spherical antenna, an insulating sleeve, an impedance-matching element, a fixed disc, a center-needle seat, and a socket member with a high-frequency connector; the impedance-matching element (inductance coil) is to be fitted in the spherical antenna and the socket member; the impedance-matching element and the socket member of the high-frequency connector form an impedance-matching network to provide a nominal capacitance; the structure not only can facilitate the assembling procedures thereof, but also can omit the test and adjustment procedures as required by the conventional antenna; moreover, such an antenna has a small size without affecting the excellent reception efficiency.
