✦ Synopsis

Abstract

A probe‐fed annular‐ring microstrip antenna with a photonic bandgap (PBG) ground plane operating in the higher order mode of TM~21~ 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 PBG ground plane used, significant improvements in the antenna performances are 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. © 2001 John Wiley & Sons, Inc.

## Abstract A novel compact microstrip antenna design is demonstrated. By embedding meandering slots in the antenna's ground plane, it is observed that the resonant frequency of the microstrip antenna is significantly lowered, which can lead to a large antenna size reduction for a fixed frequency o
