This work looks at the use of wideband cavity-backed U-slot microstrip antennas in finite phased arrays. This configuration retains the single-patch and single-layer characteristics of conventional microstrip antenna arrays and provides a good impedance matching over wider scan angles when electrica

Two wideband tapered slot antennas are designed, fabricated, and tested. The first antenna, which is fabricated on a high dielectric constant substrate (e r 5 10.2), shows a measured return loss of better than 10 dB from 1.6 to 12.4 GHz (7.7:1 bandwidth), and an antenna gain varying from 3.6 to 7.8
## Abstract A thin (only 5% of the operating wavelength, Ξ») wideband microstrip patch antenna with two closely spaced slots is introduced. When connected to each other, the two slots translate into two distinct resonant frequencies, resulting in wide impedance bandwidth (about 20% within 2:1 VSWR).
