This paper presents a slotted-rectangular patch antenna with proximity-coupled feed operated at dual band of millimeter-wave (mmV) frequencies, 28GHz and 38GHz. The antenna was built in multilayer substrate construct by 10-layers Low temperature Co-fiber Ceramic (LTCC) with 5 mils thickness each. The slotted-patch and thick substrate are configured to enhance the bandwidth and obtain a good result...
In this manuscript, double-negative transmission line (TL) metamaterial-inspired antenna has been proposed with compactness and improved bandwidth. This antenna is made of double-negative meander lines, microstrip feed and partial ground. Double-negative TL metamaterials show negative permittivity and permeability simultaneously and play important role for antenna miniaturization and the impedance...
In this paper, a paper based negative indexed metamaterial is proposed for electromagnetic absorption reduction of portable wireless devices. The metamaterial structure has been designed and characterized using FIT technique based EM simulator CST Microwave studio. The main outcomes of the paper are EM absorption reduction by 14.23% and 15.3% at 0.9 GHz and 1.80 GHz, respectively using metamaterial...
This paper presents an aperture-coupled microstrip antenna, which is operating at dual band of millimeter-wave (mmW) frequencies, 28GHz and 38GHz. The aperture antenna was integrated with multilayer substrate construct on 5-layers Low temperature Co-fiber Ceramic (LTCC) with 5 mils thickness. The driven patch was applied to enhance the bandwidth. The bandwidths using are 9.1 percent at 28GHz and 9...
In this paper, a design concept of modified rectangular shape slotted patch antenna with microstrip feed is proposed for GPS and WLAN applications. The proposed simple planar design of the planar antenna is composed of partially extended radiating surface which is loaded with L-shape slot and two wide square slots. The optimized design of the antenna has overall dimension of $$40 \times 40\; \mathrm{mm}^{2}$$...
A reconfigurable reflectarray single element and 2×2 sub-array with a single varactor embedded inter-patch are presented. A phase diagram of both configurations and the relation to a radiation pattern is analyzed. Simulated radiation patterns from three designs namely CCSR, CRP and CRG with single element phase characteristics as a reference are reported to demonstrate reconfigurability of elements...
The new antenna design of a multiband rectangular shape dielectric resonator antenna (DRA) which operates at around 1.8GHz (GSM1800), 2.2GHz (DVB-SH) and 2.6GHz (LTE-A) bands for wireless mobile communication handheld devices is discussed in this paper. The proposed DRA is designed with a size of 34mm × 33mm × 10mm and simulated by using the CST Microwave Software. The proposed antenna design, with...
Continues development of new product innovative is an important driver for manufacture to sustain in market place. Success or failures of new product in market place depend very much on how organization implementing pre-development process. However large-scale organizations have received full attention from many researchers with respect to efficient pre-development implementation and practices compared...
