A multiresonance double cross element is used to design a dual-band reflectarray with dual linear polarization. The proposed element has a single conductive layer structure which makes it easy to manufacture. The results presented in this paper show that the mutual effect between the elements of the two bands is negligible. Hence, it is easy to achieve the phase compensation for each band separ...
The basic shape structures are designed at frequency 2.4 GHz based on radiating structure 5 and 5.2 GHz based on radiating structure 3. The frequency bands that have been chosen are based on the IEEE standards. Then both structures are combined to achieve dual band resonant. The techniques that have been used are by designing the 3.5 shaped by using microstrip, planar and coplanar waveguide str...
Abstract— Miniaturized structure and multiple band performance of a patch antenna are primary requirements for modern wireless communication systems. In this paper, a novel design of monopole dual band microstrip patch antenna with circular ring has been proposed for S and C band applications. For dual bands (4.0 GHz and 4.68 GHz), proposed patch antenna shows quite satisfactory radiation perfo...
A new broadband and dual band circular slot cut modified circular microstrip antenna is analyzed and proposed. The parametric study to analyze the effects of circular slot which realizes broader bandwidth is presented. The circular slot creates two additional resonant modes near the fundamental TM11 mode resonance frequency of the equivalent circular patch and yields bandwidth of 202 MHz (8%). ...
