Low-Profile and Wideband Antenna

A novel wideband and low-profile planar dipole antenna is proposed. Matching structures that can make the antenna operating band wider and parasitic structures that can make the antenna of low profile are introduced. For verification, the proposed antenna prototype with a height of 30 mm (0.1 wave- length at the lowest frequency) was fabricated and measured. It is shown that the VSWRs of the antenna are less than 2.0:1 over 0.99-2.08 GHz. The radiation performance is good over the whole frequency band.
