How to Write a Summary of an Article? Such as GPS and K-PCS, The multi-hand antennas with one feeding pon use the multiple resonance technolagy[l] such antennal are difficult lo provide a good polarization efficiency for GPS signal reception.
Referenced dual-band antenna using two feeding pon has matched poiariration of integrated system. Proposed antenna uses miniafurizalion technique that is to insect ilits.
This technique is to increase elecVlcal surface length by slits. The proposed antenna composed of a low-profile cylindrical monopole with a top-loaded meander line patch for K-PCS Operation, and a comer-truncated square-ring microstrip patch antenna with four-slits for GPS ooeration.
The proposed antenna has the common ground plane, but i s fed by separate feeding pon. The antenns for GPS-hand i s realized by using a corner-truncated square-ring microstrip patch with four slits.
The middle ofthe substrate is removed for inner rectangular d i t area b x b of patch. Feed position for right-hand circularly polarized RHCP wave operation is placed along x-axis. The four-rlitr at the comers are of equal length I3.
Fig 2 a shows simulated reNm loss of the proposed anlenna for GPS receiving antenna with various d i t lengths S. It i s noted that the reSonant frequency rapidly lowered with increasingdesign parameter S. For brbadband characteristic, cylindrical monopole has a large diameter of 6.
The eander line patch has a ride lengh Z l m m p and is connected to the common ground by two same shorting posh, which have a diameter of 2. By varying ofthe shorting ports diameter d2good impedance matching can easily be obtained. Meander line patch size can be reduced by increasing inserted slit length.
According to the experiment, the patch size of GPS antenna for circular polarized operation must he over about twice the size of KPCS antenna with meander line suunurc. The measured axial ratio ofthe antenna for GPS operation i s presented in Figure 3.
JdBi, for GPS operation the measured peak antenna gains is about 7. A low-profile cylindrical monopole with a shorted meander line patch i s loaded for K-PCS operation, which rhowr a linearly polarized monopole patkm with broadband characterirlic. The radiating clement for GPS operation is a novel square-ring microstip path with truncated comers with four slits, which provide circularly polarized braadrids radiation panemr.
Meander line patch and square ring patch with four. As the proposed antenna has a compact size for dual band operation, it will be suitable for practical vehicular mobile communication antenna applications. The measured arid ratio. Fig 1 Measured r t b m loss of antenna.In this paper a dualband suspended microstrip right-angled isosceles triangular patch antenna is designed for use in microwave imaging system for breast cancer tumour detection.

This paper presents design and simulation of a rectangular microstrip patch antenna at GHz for wireless communications.
This antenna has MHZ bandwidth, Return loss at centre Thus the design and simulation of Microstrip rectangular patch antenna was successfully designed and analyzed using Ansoft HFSS. The performance parameters . Abstract: The purpose of this paper is to design a microstrip rectangular antenna in Advance Design System Momentum (ADS).
The resonant frequency of antenna is GHz.
The reflection coefficient is less than dB for a frequency range of GHz to GHz. The proposed rectangular patch antenna . Singh, S. PhD thesis bar admission essay writing middle school phd thesis.
