Compact microstrip slot antenna for broadband operation

An arrow-shaped microstrip antenna with a pair of narrow slots embedded near the non-radiating edges gives wide impedance bandwidth. The experimental and simulated (IE3D) results show that antenna bandwidth is ∼3.5 times that of a conventional patch with the added advantage of reduced antenna size. The radiation characteristics are found to be uniform throughout the operating band. © 2003 Wiley Periodicals, Inc.
