design and implementation of the planar inverted-f antenna using computer simulation technology for wireless applications

The planar inverted-f antenna (pifa) is becoming more popular in the new multi-band mobile phone industry fortransceiver systems of wireless communication systems. the purpose of this paper is to design and implement aplanar inverted-f antenna for wireless communication. this device can work in the s-band resonance frequency range.because the antenna is a quarter wavelength, the antenna size and return loss are reduced. the practical results ofthe used antenna showed that the return loss is about 34.20 db, the voltage standing wave ratio(vswr) is 1.18258,and the bandwidth is 220 mhz. theoretically, the directivity, gain, and input impedance values were also calculatedas 5.617 db,5.247 db, and 50 ω, respectively. therefore, the desired antenna is considered to perform well in termsof return loss and voltage. it can be utilized in bluetooth, wi-fi, and long term evolution (lte) applications infourth-generation cellular communications (4g).
