Nonuniform Semi-patches for Designing an Ultra Wideband PIFA Antenna by Using Genetic Algorithm Optimization


The planar inverted-F antenna (PIFA) is widely used in mobile and portable radio devices due to its good performance. However, it is rarely used as an ultra wideband antenna due to its narrow band characteristics. In this paper, we propose a new method of designing the ultra wideband PIFA antenna by using a genetic algorithm. The radiating plate of the proposed antenna is optimized by using three different sizes of rectangular semi-patches. The genetic algorithm optimization is used to define the location and the size of the suitable semi-patches in order to achieve an ultra wideband PIFA antenna. The suggested antenna is a new ultra wideband PIFA antenna with nonuniform semi-patches for Wi-Fi/Bluetooth/LTE/WLAN/WIMAX/HIPERLAN-2/5G applications with a very large bandwidth (\(S_{11} <-6 \mathrm{dB}\)) starting from 2.3 to 6 GHz to cover the major part of the mobile phone frequencies. Three operating resonance frequencies appeared at 2.4 GHz, 3.95 GHz, and 5.13 GHz. All these three resonant frequencies show better impedance matching with convenient gain and omnidirectional radiation pattern. The proposed PIFA antenna design is printed on a substrate named FR4 epoxy and having a total dimension of 30 \(\times\) 15 \(\times\) 5.4 \(\mathrm{mm}^3\). Besides, the proposed ultra wideband PIFA antenna has a compact size and achieved a good performance, which makes it appropriate for mobile in several applications.
