Novel Design of Penta Band Planar Inverted F Antenna for Wireless Communication

Abstract

In this paper, a novel penta-band internal single feed low profile Planar Inverted F Antenna (PIFA) that operates in several bands including Global System for Mobile Communication GSM 900 MHz, GSM 1800 MHz, Global Positioning System (GPS), Universal Mobile Telecommunications Service UMTS 2100 MHz, 1800 MHz, Advanced Wireless Services AWS 1700 MHz and Industrial, Scientific and Medical Band ISM 2.4 GHz has been proposed. The proposed antenna has a rectangular and slotted radiating patch suspended above a rectangular ground plane, which is also slotted. A 0.6 mm thick FR4 dielectric substrate of the same size as the rectangular ground plane has been used between the radiating patch and the ground plane. By optimizing the slots on the radiating patch as well as the ones on the ground plane, it has been noticed that the antenna can work at five distinct bands of frequencies with good operating bandwidth. The slots on the ground plane have contributed further to generate multiband frequencies with improved bandwidth and to form almost omnidirectional radiation patterns at the resonating frequencies. The simulation and the analysis of the proposed antenna have been done using Computer Simulation Technology (CST) Studio Suite software. This novel compact penta band PIFA antenna shows very good performance at all the frequencies of operations and it will be a suitable candidate for wireless communications.
