The single wire fed dipole on slab: an antenna for integration with monolithic microwave and millimeter wave circuits

An experimental investigation of a simple antenna element suitable for integration on the substrate of a MMIC (monolithic microwave integrated circuit) is presented. These antennas are intended for use in egg-crate type arrays. The structure occupies a small area of the substrate, is fed directly from a microstrip transmission line, and is therefore cheap to produce. This cost effectiveness is obtained at the expense of cross-polarization performance. In terms of gain, beamwidth, and bandwidth, this antenna appears to be quite attractive for use at millimeter wavelengths in large phased arrays.<>
