This paper designed a miniaturized Planar Inverted-F Antenna for 5G communication networks, including Long-Term Evolution Advanced mobile communication services. By showing the radiation pattern, voltage standing wave ratio, and antenna gain of the designed Planar Inverted-F Antenna, this paper evaluates its performance. To show the key characteristics of the Planar Inverted-F Antenna, this paper modeled and simulated it with various variances. Moreover, the real Planar Inverted-F Antenna was fabricated and measurements were done to validate the simulated characteristics of the internal antenna.

In this paper, we present a compact high-efficiency multi-band micro strip antenna for the mobile devices. At the same time, because most of antennas are located near the ground planar, the proposed antenna is designed with a ground planar. The antenna occupies a small size of 100*60mm2 and operates in CDMA(824-894MHz),GSM(880-960MHz), DCS(1710-1880),PCS(1850-1990),UMTS(1920-2170) and 3G band. By using a long slot, two trapezoid slots and a short slot, a triple resonance around 900MHz and another wideband resonance around 2100MHz can be created, respectively. Details of the antenna design are described , and its radiation performances results are presented and discussed. Keywords-Multi-band antenna;; mobile communication devices; hige-efficency

In this research, the aim is to design and implement a new low noise amplifier (LNA) for a multi-standard mobile receiver based on reconfigurability concept. The LNA design is based on the inductively-degenerated common-source (IDCS) topology as it has been proven to be a good choice in designing multi-standard multi-band LNA. The design is using 0.18 µm CMOS technology. The reconfigurable LNA has been designed to operate in two bands of standards consisting the bands range from 800 to 1000-MHz (lower band) and 1800 to 2200-MHz (upper band). The simulation results exhibit gain S21 of 12.9-dB for lower band and 12.4-dB for upper band, input reflection S11 of -14.5-dB and -17.2-dB for both bands, and output return loss S22 of -14.7-dB and -26-dB for lower and upper band making the LNA suitable for most of the mobile communication applications. The LNA also exhibits the noise of figure of 2.55-dB and 2.3-dB for lower and upper band respectively. The circuit consumes 26.5 mW when operating in lower band mode and uses 18.8 mW of power when operating in upper band mode.
