Abstract

In this letter, we propose a compact spiral stripline‐loaded monopole antenna on a vertical ground plane. The measured results show that the antenna has a fractional bandwidth of 12.1% for a voltage standing wave ratio (VSWR) less than 2 at the center frequency of 1.10 GHz, as well as a good omni‐directional radiation pattern. The small size of 0.04 λ~o~ × 0.04 λ~o~ × 0.04 λ~o~ makes it promising for use as an internal antenna in mobile handsets. © 2007 Wiley Periodicals, 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
