Compact Slotted Antenna for Wideband Radar Applications
A new type of slotted microstrip antenna, suitable for wideband radar applications, is proposed in this work. The standard U-slot shape, usually adopted to enlarge the operating bandwidth of a microstrip patch, is properly modified to reduce the undesired cross-polar effects, while providing also a significant size reduction. Validations on X-band and P-band, useful for radar applications, are successfully discussed. In particular, a P-band prototype has been manufactured and tested, while the numerical simulation results of an X-band antenna, performing a 45% bandwidth, are successfully reported.
