This paper investigates a technique to design small size UWB antennas. The technique is named as Relative Size Reduction Technique (RSRT). The technique has been applied to three reference antennas, and it is observed that maximum reduction of about 53% in the antenna size is achieved without significant deterioration in antenna radiation properties. It is also shown that this technique works equally...
This paper presents a parametric study of a UWB antenna loaded with parasitic patches on the front and metal sheets as reflectors on the back side. A maximum increase of 2.6dB in gain with a maximum gain of 10.4dBi was observed by increasing the number of parasitic patches but keeping their sizes fixed. Similarly by varying the size of the parasitic patches, gain increased by 5dB. Finally increasing...
A novel technique for miniaturization of microstrip patch antenna is proposed for Portable and multifunctional Communication systems. Our proposed design consist of U-Shaped slot on fractal patch with first iteration and combination of L-Shape and U-Shape slots on the Ground plane. We also utilized shorting Pin between patch and ground plane. In this way we get smaller size antenna which is 89% smaller...
