- Abstract
- In this article, a novel compact internal wideband planar inverted F-antenna (PIFA) was designed. The proposed antenna consisted of a main patch with strip, rectangular slot, and shorting strip and occupied the total volume of 36 X 18 X 6 mm(3). The dual band characteristic was achieved by changing the length of a main patch. A wide impedance bandwidth property was obtained by optimizing the length of shorting strip. The measured 6 dB return loss bandwidths were 22% at 977 MHz and 52.4% at 2025 MHz respectively. The maximum gains at 915, 1785, 2045, 2450, and 2630 MHz were -0.48, 4.28, 2.79, 1.05, and 1.22 dBi, respectively. The overall radiation patterns are suitable for mobile communication application.
