The Cost

In the last few decades, the evolution in new-fashioned wireless communication systems has actuated augmented exploration on uncomplicated dual band antennas. In this paper, a dual-band half psi shaped antenna for WLAN, Wi-Fi and WiMAX appliances is designed and analyzed. The intended antenna constitutes a half psi shaped radiating patch on the cost effective FR4-substrate with 1.6 mm thickness. A 50 ohms feed line is employed to feed half psi shaped antenna. Here a preferable impedance matching is attained by truncating a portion of the ground surface. The intended antenna has the potential to resonate between the frequency bands of 1.88 GHz-2.75 GHz and 5.17 GHz-5.74 GHz with S11 below -10 dB. The design of the antenna and its behavior over various frequencies ranges is done with the use of HFSS. The proposed antenna has higher gains at two regions. The simulated antenna is also prototyped and a fine similarity is attained in between the simulated parameters and measured parameters.

Over the past few decades, the evolution in new-fashioned wireless communication systems has actuated augmented exploration on uncomplicated dual band antennas. A compact dual band mono pole antenna for UWB and Ku Band Applications is proposed. The antenna consists of a corner truncated rectangular patch etched on cost effective FR4-substrate with thickness 1.6mm and is fed with 50 ohms feed line. The ground plane is truncated to enhance impedance matching and bandwidth. The proposed antenna has the ability to operate from 3.40 GHz to 10.67 GHz and 13.48 GHz to 15.87 GHz with return loss below -10 dB. The HFSS is used to design and simulate the antennas behavior over the different frequency ranges. The simulated results of the proposed antenna indicate higher gain at the two bands. The measured results demonstrated reasonable agreement with the simulated results

Due to the progression growth of multiservice wireless communication systems in a single device, multiband bandpass filter has attract a great attention to the end user. Therefore, multiband bandpass filter is a crucial component in the multiband transceivers systems which can support multiple services in one device. This paper presents a design of dual-band bandpass filter at 2.4 GHz and 3.5 GHz for WLAN and WiMAX applications. Firstly, the wideband bandpass filter is designed at a center frequency of 3 GHz based on quarter-wavelength short circuited stub. Three types of defected microstrip structure (DMS) are implemented to produce a wide notch band, which are T-inversed shape, C-shape, and U- Shape. Based on the performance comparisons, U-shaped DMS is selected to be integrated with the bandpass filter. The designed filter achieved two passbands centered at 2.51 GHz and 3.59 GHz with 3 dB bandwidth of 15.94 % and 15.86 %. The proposed design is very useful for wireless communication systems and its applications such as WLAN and WiMAX

The Look

“In this paper FPGA based hardware co-simulation of an area and power efficient FIR filter for wireless communication systems is presented. The implementation is based on distributed arithmetic (DA) which substitutes multiply-and-accumulate operations with look up table (LUT) accesses. Parallel Distributed arithmetic (PDA) look up table approach is used to implement an FIR Filter taking optimal advantage of the look up table structure of FPGA using VHDL. The proposed design is hardware co-simulated using System Generator10.1, synthesized with Xilinx ISE 10.1 software, and implemented on Virtex-4 based xc4vlx25-10ff668 target device. Results show that the proposed design operates at 17.5 MHz throughput and consumes 0.468W power with considerable reduction in required resources to implement the design as compared to Coregen and add/shift based design styles. Due to this reduction in required resources the proposed design can also be implemented on Spartan-3 FPGA device to provide cost effective solution for DSP and wireless communication applications.”

Reconfigurable Filters

The new design methods of microwave filter has proved its significance for use in wireless communication systems. Modern wireless communication systems require microwave filters to have stringent specifications such as compact size, robust, conformal, light weight and more importantly cost effective while maintaining its electrical characteristics. Micro-strip filter design and reconfigurable filters present a better prospectus in this regards as it meets the specifications of modern wireless communication applications. Reconfigurable filters can provide control over parameters such as frequency, bandwidth and selectivity while reducing the need of number of switches sandwiched between electrical components. Different methods have provided a new dimension for designing microwave filters .In this article, we present a review on design methods for reconfigurable band-pass filters for next generation wireless technologies such as 4G, 5G and IOT.
