This article proposes a quad band patch antenna for mobile communication. The design requirements are to meet the 0.9 GHz, 1.8 GHz, 2.1 GHz and 2.45 GHz bands. The proposed antenna consists of a rectangular patch monopole printed antenna in which slotting technique is used to achieve multi band resonance. The Patch with three slotted lines generates four resonating frequencies to cover 0.9 GHz ...

The design process of antenna structures that meet up-to-date requirements takes a long time and brings high computational load. In this paper, an approach based on Soft Computing (SC) techniques was used to shorten the achieve structure yields performance characteristics as close possible desired values. order obtain microstrip patch with targeted best accuracy in faster way, Support Vector Ma...

This paper presents a slotted planar microstrip patch antenna for the 5th generation communication. The is designed with square and two longitude slots at 3.5 GHz, using FR4 substrate feds by coplanar waveguide structure (CPW). proposed was simulated, analysed, optimized computer simulation technology (CST) software. Simulation results show good return loss of greater than10 dB impedance bandwi...

In this paper, a simple method of enhancing the bandwidth Bell-shaped UWB Antenna for indoor localization systems is proposed. Therefore, modified version bell-shaped Ultra-Wide Band (UWB) antenna presented. The proposed printed on low-cost FR-4 substrate 21×27×1.6mm3 size. It composed radiating patch and multi-slotted ground plane. measured results show that has an impedance about 11.2GHz rang...
