The evolution of the modern wireless communication system has increased the demand of antennas, which can work on number of frequencies and should have large bandwidth to accommodate more number of channels. A high gain, wide band Ku-band antenna is realized and simulated using ADS (Advance Design Systems) simulation tool. The purposed design uses inset feed for proper impedance matching. The designed antenna has width of the patch, Wp = 49.4mm and length of the patch, Lp = 41.4mm. Taconic TLY-5 dielectric substrate is used as a substrate layer, which has dielectric constant of 2.2, and height of dielectric substrate is 1.6mm. The advantages of the resultant configurations are a) design is simple b) high Gain c) the structure remains single layer and single patch d) large bandwidth e) miniaturized size. The designed antenna provides 3.72 GHz bandwidth ranges from 11.86 GHz to 15.58 GHz at10dB return loss. For Ku-band it can be used for terrestrial microwave and radar, especially police traffic speed-detector.
This paper gives the design of Yagi-Uda antenna using microstrip circuit. Microstip circuits are used to implement Yagi-Uda antenna so as to reduce the size but here we have shown only two optimization technique. This has been done by varying the length, width and spacing between reflector, driven element and directors. Simulations are conducted to show how return loss and other parameters vary by varying the above mentioned Yagi-Uda parameters. This antenna is operating very near to resonant frequency fr = 2.4 GHz with the specification relative permittivity ε r = 3.2, height of substrate h=1.6mm, characteristic impedance Z 0 = 50 ohm and thickness of strip conductor t=35um. In this paper, two most approximate results after all these perturbations are analyzed and simulations showing return loss and other parameters like directivity, gain and power radiated are discussed. The simulation process has been done using Advanced Design System (ADS) tool.
A novel design of the microstrip patch antenna is being proposed in this work. The patch antenna has been designed starting from rectangular patch with rectangular ground and ending with an umbrella semicircular shape for both the patch and a ground plane at an operating frequency of 5 GHz in order to enhance the bandwidth of the antenna using HFSS. On simulation it was observed that the -10dB impedance bandwidth of antenna increased from 15.94% to 43.07% showing the improvement of 27.13% with return loss of -37.77 dB with good VSWR. The semicircular patch with modified circular ground produced a bandwidth of 2.1537 GHz which can be used for the ultra-wide band (UWB) applications.
