“…The PIFA380LDE, microstrip antenna has two compact short circuits connected to the ground plane [5]. The short introduces a return path for the surface currents of the antenna and triggers resonance for electrical dimensions smaller than half-a-wavelength [24,25]. The experimental and simulated results show that these short are responsible for the radiation patterns in the frequency resonances searches and are shown in Figure 9(a-c).…”

A new planar triple band microstrip‐fed Planar Inverted‐F Antenna (PIFA) for the use in GSM835 band (698–989 MHz), DCS1940 band (1824–2033 MHz) and Wi‐Fi2340 band (2302–2548 MHz) is reported. A numerical study based on the parameters like ground plane length, height of radiating plate, feeding point position, shorting plate width, and position, was done to obtain an optimized antenna. The simulation allowed the characterization of the designed antenna as a function of different antenna parameters like S11, resonant frequency, bandwidth, gain, radiation pattern, and electric and magnetic fields distribution. A prototype was fabricated and the agreement with the simulations study was very good. The measured bandwidth of 34.73%, 48.47%, and 38.21% were obtained, respectively. The gain of 4.02 dBi, 2.47 dBi, and 4.93 dBi was also obtained for each band, respectively. The antenna also presents high efficiency of 53.19%, 49.07%, and 62.21%, respectively. The reported results show that this PIFA is suitable for mobile‐communication applications. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2960–2965, 2016

“…The relative permittivity Er of the substrate, together with the thickness h of the microstrip antenna, has a considerable impact on the resonant frequency, gain, polarization, and matching of an antenna. There is a significant reduction in the microstrip antenna performance when Er increases, because the antenna size reduces with high performativity substrates at the expense of the matching bandwidth and antenna gain [20]. Furthermore, the loss tangent has a large impact on antenna gain and performance.…”

Micro strip patch directional antennas are an attractive solution for modern wireless systems due to their high gain and directivity. Being an attractive solution creates the need to design such devices for various application scenarios. We have addressed that need by designing, simulating, and testing a rectangular microstrip patch directional antenna at 5GHz. Antenna patch and ground plane were designed with the well-known guided wavelength equation. The antenna performance, in terms of return loss at -10dB, gain, bandwidth, and the radiation pattern was analyzed with a simulation model. The proposed antenna achieved an impedance bandwidth of 77.8MHz (from 4.9662GHz to 5.0440GHz) and a gain of 6.26dBi at 5GHz. The antenna performance was verified with a software defined radio platform. We found that the software radio measurements confirmed the key simulation results. Furthermore, the extensive use of simulation enabled us to develop both antenna and digital baseband algorithms in parallel.

The rapid progress in wireless communication systems and handheld terminal devices has made the implementation of small multi-band antennas one of the main technical challenges. The number of wireless systems in which multimode mobile terminals are required to operate has been growing constantly in recent years. Nowadays handheld terminal phones use various cellular bands (GSM850/900/1800/1900 + 3G/4G/5G), wireless LAN, Bluetooth, Digital TV (DVB-H), FM radio, GPS, RFID, UWB, and WiMAX. The narrow bandwidth constitutes the major disadvantage of microstrip antennas in most practical applications. This study proposes a new wideband small size flower-shaped PIFA antenna. The PIFA design has newest flower structure and is supported by two or three shorting pins. The layer patch is slotted by Allah name in Arabic ‫.)اﷲ(‬ A capacitive feeding of the antenna was done via 50 coaxial cable to achieve impedance matching. The simulation was done using the high frequency HFSS10 simulator for different scenarios. Simulated results on the return loss, the radiation pattern, and the gain are promising. The devised antenna could be implemented in many wireless communication standards such
