A broadband low‐profile cylindrical monopole antenna top‐loaded with a shorted circular patch is presented. The shorted circular patch is connected to the antenna ground by two shorting cylinders placed symmetrically on each side of the cylindrical monopole. Experiments have been carried out, and obtained results show that, with an antenna height only about 0.07 times the free‐space wavelength of the center operating frequency, the proposed antenna can have a monopole radiation pattern with an impedance bandwidth of 14.8%, which is much greater than that (3%) of a corresponding monopolar wire‐patch antenna. © 2001 John Wiley & Sons, Inc.
