Abstract

This letter presents the design of a planar single-layer wideband antenna featuring wide beamwidth has well as high and stable in-band gain. The proposed antenna is a planar monopole fed by a bottom-grounded coplanar waveguide to realize wide beamwidth in both the <italic>xz</italic>- and <italic>yz</italic>-planes. Simultaneous optimization of all adjustable antenna parameters, carried out at the full-wave electromagnetic simulation level.The constructive interference of the radiated fields resulting in impedance bandwidth of more than 2 GHz, from 27 GHz to 29 GHz. Along with a stable realized gain (&gt;11 dBi) in the operating frequency band.The proposed antenna maintains adirectional radiation pattern in the broadside direction. Merging the radiated modes of the slots and the parasitic patch elements also extends the antenna beamwidth to roughly &#x00B1;35o with respect to the broadside direction. Following a detailed theoretical analysis, the antenna is validated numerically and experimentally, both in the free spaceand on ahuman volunteer chest and arm.
