This paper presents compact structure of bandpass filter integrated with Defected Microstrip Structure (DMS) to produce band-pass and band reject response simultaneously. The filter design based upon λg0 short-circuited stubs structures of 7th degree. The narrow notch responses produced by DMS was introduced at a frequency of 5.2 GHz in order to reject any undesired signals which may interfere with...
This paper studies a wideband antenna of ice-cream cone structure and it is integrated with a rectifying circuit which has the potential to be used for RF energy harvesting system. The antenna is designed by using CST Studio Suite 2011 and fabricated on a double sided FR-4 printed circuit board using an etching technique. A single stage rectifying circuit is designed, simulated, fabricated and measured...
In this work, a novel coplanar waveguide (CPW) fed rectangular patch antenna embedded with four L-shaped slots for WiMAX application was proposed. This antenna is designed by using an FR4 epoxy board with dielectric constant, εr = 4.4, tangent loss, tan δ = 0.019 and the thickness of substrate, h = 1.6mm. There are two methods applied in this antenna to improve the characteristic of the antenna. The...
In this work, a dual layer rectangular microstrip patch antenna with H-slot is proposed for improving the return loss and enhanced gain at 2.4 GHz and 2.45 GHz. The antenna is designed by using CST Microwave Studio is used to design the mathematically based on the rectangular microstrip patch antenna. Simulated and experimental results obtained for this antenna show that it exhibits good radiation...

In this paper, a printed two C-shaped monopole antenna array for dual-band WLAN application is presented. The proposed antenna array contains two C-shaped monopole with a shorting line for connecting the two arms of the antenna elements. The purpose of the shorting line is to neutralize the current between the two arms which in return can increase the isolation. A parametric study was also carried...
