This paper investigates an H-fractal wideband microstrip filter with multi-passbands and a tuned notch band for wireless communication frequencies. The four different filter configurations explored are: symmetric with zero offset, symmetric with nonzero offset, asymmetric with zero offset, and asymmetric with nonzero offset. The effect of H-fractal iterations, fractal scaling parameters, and st...

In this paper, an end-fire microstrip patch antenna (MPA) is proposed of 3 GHz as a center frequency, designed, simulated, and measured to work on WiMAX frequencies within standard 802.16e (WiMAX). A high gain ranged between (12.117-13.324) dB, front back ratio (F/B) (35.770) at the wide band 1.701 GHz, low profile, semi-ideal voltage standing wave (VSWR) 1.053 achieved. The simulation done usi...

A small antenna with single notch band at 3.5 GHz is designed for ultrawideband (UWB) communication applications. The fabricated antenna comprises a radiating monopole element and a perfectly conducting ground plane with a wide slot. To achieve a notch band at 3.5 GHz, a parasitic element has been inserted in the same plane of the substrate along with the radiating patch. Experimental results s...

In this research, a 1x2 circular patch microstrip array antenna with feeding line is made which can be used on WiFi and WiMax work at frequencies of 2.4, 3.7 5.8 GHz. This design uses Ansoft HFSS software. Where the simulation results frequency 2.4 GHz obtained return loss value -22.28 dB, -19.03 dB -14.94 for GHz, VSWR 1.17 1.25 3, 7 1.43 GHz.Gain 1 directivity 2,33 dB. The show that parameter...
