Abstract
There is disclosed an antenna arrangement comprising an electrically conductive radiating element having first and second ends, an electrically conductive ground plane or ground member, and an input terminal. The radiating element has a plurality of separate feed points at different locations between its first and second ends, and the input terminal is provided with a switch. Each feed point is electrically connected to the switch by way of a separate electrical pathway, the switch being configured to allow the separate feed points to be connected individually or in predetermined combinations to the input terminal by selecting between a plurality of selectable contacts. At least one of the electrical pathways includes a capacitive circuit component connected in series, and at least one other of the electrical pathways includes an inductive circuit component connected in series. The antenna arrangement allows for a high degree of customization and improved matching, and enables good multi-band performance.
