Broadband shorted patch antenna with monopole-like radiation patterns

The design of a shorted square patch antenna with broadband operation is presented. By placing an additional shorting wall at the edge of a planar inverted‐F antenna (PIFA) with a U‐shaped slot, the antenna can provide stable monopole‐like conical radiation patterns within the operating bandwidth. A...

Summary:The design of a shorted square patch antenna with broadband operation is presented. By placing an additional shorting wall at the edge of a planar inverted‐F antenna (PIFA) with a U‐shaped slot, the antenna can provide stable monopole‐like conical radiation patterns within the operating bandwidth. An antenna prototype designed for IEEE 802.11a band is completed and tested. The measured results show the 10 dB impedance bandwidth of more than 30% can be obtained while the side length of the square patch is about 0.3 free‐space wavelengths and the antenna height is less than 0.08 free‐space wavelengths. © 2006 Wiley Periodicals, Inc.
