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

This paper presents a multiple-resonance technique that sought to achieve a wide bandwidth for printed wide-slot antennas with fork-shaped stubs. By properly appending an extra fork-shaped stub onto the main fork-shaped stub, the impedance bandwidth was able to be clearly broadened. To validate this technique, two designs where the extra stubs were added at different positions of the main stub were constructed. The measured impedance bandwidths of the proposed antennas reached 148.6% (0.9–6.1 GHz) for S11 < −10 dB, indicating a 17.9% wider bandwidth than that of the normal antenna (0.9–4.3 GHz). Moreover, a stable radiation pattern was observed within the operating frequency range. The proposed antennas were confirmed to be much-improved candidates for applications in various wireless communication systems.

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.
