Abstract
An antenna assembly has a pair of disk-shaped antennae each tuned to a different frequency band thereby enabling the same antenna to be used to different types of communication equipment, such as cellular and PCS telephones. The first antenna has a first substrate with first and second conductive layers applied to its major surfaces, and the second antenna has a second substrate with third and fourth conductive layers applied to its major surfaces. A primary shunt extends between the first and second conductive layers to tune the first antenna, and a secondary shunt extends between the third and fourth conductive layers to tune the second antenna. The first and second antennae abut with the first conductive layer contacting the fourth conductive layer. A pair of electrical conductors are connected to different ones of the second and third conductive layers to carry communication signals to the antenna assembly.
