The compact designs of a shorted triangular patch antenna embedded with a V slot are proposed and studied. A broadband V‐slotted triangular patch antenna with one shorting wall is initially constructed as a reference. By inserting an additional shorting wall to this reference antenna, a new broadband operation can be obtained and its operating frequency is decreased by 22%, which corresponds to a reduction of 40% in the antenna area. The antenna area can be further reduced by symmetrically halving the patch size, and it is found that the impedance bandwidth of the broadband operation demonstrated no obvious variation and the operating frequency is only increased by around 8%. Details of the antenna designs and obtained results are presented. © 2006 Wiley Periodicals, Inc.
