摘要：
A probe-Sed annular-ring microstrip antenna with a photonic bandgap (PBG) ground plane operating in the higher order,node of TM21 for conical-pattern radiation is experimentally demonstrated. The antenna studied is printed on a thin FR4 substrate (relative permittivity 4.4) and, owing to the PEG ground plane used, significant improvements in the antenna performances ar e observed. The obtained impedance bandwidth is doubled, and the antenna gain is enhanced by about 7 dBi. Details of the experimental results are presented and discussed. (C) 2001 John Wiley & Sons, Inc.
