Multiband top loaded monopole antenna

摘要

An apparatus (100) includes an antenna (102) (e.g., a monopole antenna), a first load (110), and a second load (112). The antenna (102), which extends substantially along an axis (103), has a first end (104) and a second end (106). The first load (110) is coupled to the antenna at the first end (104), while the second load (112) is coupled to the antenna (102) between the first end (104) and the second end (106). Both the first and second loads (110, 112) are symmetrical with reference to the axis. The apparatus is arranged to operate in at least two frequency bands, such as the Advanced Mobile Phone System (AMPS) band from about 824 MHz to about 894 MHz and the Personal Communications Service (PCS) band from about 1850 MHz to about 1990 MHz. The antenna (120) and first and second loads (110, 112) may be formed on the surface of a printed circuit board and may be symmetrically disposed relative to the axis (103)
