Simulated design and analysis of miniature stub-loaded omni-directional monopole antenna at 800 MHz for Forward Scattering Radar (FSR) sensor is presented in this paper. A miniature technique and a robust genetic algorithm optimizer have been introduced to minimize the total length of the antenna compares to a standard monopole antenna at same frequency.(More)
A novel compact size of reconfigurable E-shaped microstrip single patch antenna was designed and analyzed for dual-band at 3.02 GHz and 6.38 GHz frequencies. The basic antenna was designed to operate at 3.02 GHz and with reconfigurability in frequency, it will operate at 6.38 GHz. The physical parameters of the novel structure as well as its partial ground(More)
Studies on the performance of an aperture coupled microstrip line-fed patch antennas on low temperature co-fired ceramic (LTCC) operating at unlicensed 5.8 GHz frequency band is presented. Observation on the controlling parameters of the aperture coupled antenna on LTCC is conducted to investigate the effect of aperture slot at various layers with different(More)
In this paper the parametric study of integrated rectangular stacked microstrip antenna with Light Emitting Diode (LED) for Wi-Fi application is presented. There are two objectives in this design: one is the analysis of when the LED placed at difference layer from the radiating patch, another one analysis is by looking at the electrical connection of 18(More)
This paper presents a novel design of aperture coupled microstrip antenna (ACMSA) integrated with DGS and parasitic elements. The basic design of the proposed antenna is 2 by 2 planar array with aperture coupler feeding technique. Four dumbbell-shaped DGS are etched on the ground plane, for back radiation reduction, which is sandwiched between the upper and(More)
In the recent era of wireless communication, Microstrip antenna (MSA) is hot research topic attracting attentions of many researchers. But MSAs have few foremost drawbacks viz narrow impedance Axial Ratio Bandwidth (A. R. BW), low gain and power handling capability. To overcome these drawbacks, novel hybridization method is proposed. A hybridization method(More)
In this paper, a 10 GHz multilayer antenna with proximity coupled feed using Low Temperature Co-fired Ceramic (LTCC) technology is presented. The multilayer antenna was designed to operate at 10.01GHz with return loss of -11.523283 dB. The antenna was simulated using CST Microwave Studio. The performance of the antenna in terms of antenna radiation pattern(More)
This paper investigated the capability of Electromagnetic band gap (EBG) in reducing the backlobe of the microstrip patch antenna array. Four different size of EBG have been simulated and the radiation patterns are presented. The results show that if only one slot of antenna is inserted into the structure, (3mm×6mm) EBG produced the best back lobe(More)
