ANTENNA WITH DUAL BAND LUMPED ELEMENT IMPEDANCE MATCHING

摘要

An antenna includes a first antenna element (112-1 in Figure 3B) and a second antenna element (112-2). The first antenna element (112-1) and the second antenna element (112-2) are both configured to receive signals in a first band of frequencies and in a second band of frequencies. Frequencies in the second band of frequencies are greater than frequencies in the first band of frequencies. A first impedance matching circuit (350-1 in Figure 3B), coupled to the first antenna element (112-1), includes a first plurality of filters having a first shared component. A second impedance matching circuit (350-2), coupled to the second antenna element, includes a second plurality of filters having a second shared component. A feed network circuit (300) is coupled to the first impedance matching circuit (350-1) and to the second impedance matching circuit (350-2) and has a combined output corresponding to the signals received by the first antenna element (112-1) and a second antenna element (112-2).
