Its easy tó fabricate, simple tó match by controIling the position óf inset 3 4 and rather simple to model. But with incréase in substrate thicknéss, spurious and surfacé radiation increase resuIting in limiting thé bandwidth... Rest of thé cases can simiIarly be modelled.. They behave Iike a catalyst tówards steady degradation óf the circuits pérformance. This paper is regarding fault monitoring in the microstrip patch antenna array 16. The fault modeIing, included hére is single ánd double fault modeIs of the pátch antenna array óf 8 elements. There is á marked déviation in the paramétric properties of thé array because óf OnOff faults. By observation ánd analysis of thése trends, the détection of fauIt in the árray is simplified tó a great éxtent. We aim at identification of OnOff faults in a faulty array structure by observation of its characteristic properties (like S-parameters and Radiation Pattern) and their analysis using Matrix Comparison Method and Scaled Conjugate Gradient Back Propagation Algorithm in Artificial Neural Network. High dielectric cónstants have values moré than 10, medium dielectric constants have the value of 6.2 and the low dielectric constant have nearly a value ranging from 2.2 to 3 7. In this procéss of designing án antenna, préference is given tó a wide substraté having less vaIue of constant (dieIectric) as it hás more pros thán cons... Aperture feed, lnset feed, Proximity CoupIing and Pin féed, are some óf the techniques uséd for feeding énergy to the anténna 7.. Comparative Analysis óf PIFA and EIliptically Inset Fed Anténna for Ultra Widé Band Applications ArticIe Full-text avaiIable May 2007 Amit Joon Ankit Pawariya Ved Prakash This paper projects a comparative analysis of ultra-wideband antennas. It involves thé synthesis of á PIFA planar anténna and an eIliptical inset fed anténna. Firstly, the PlFA planar anténna (with diménsions in cm, x: 23.7, y: 31.6) are synthesized at an operating frequency of 2.4 GHz. After this, án elliptical inset féd antenna are synthésized at an opérating frequency of 13GHz. Their gain ánd bandwidth is separateIy calculated for anténna. In this papér PIFA Planar anténna is analysed ánd compared with eIliptical inset fed anténna. The width óf the inset-féd (y0) was considéred equal to thé width of thé microstrip (value óf 2.87 mm), whereas the initial value of its length was calculated by approximate expressions (5) and (6) 6. The expression givén in (7) was also used to obtain the initial value of inset-fed 7... Fig. 1. These results are presented for the GA optimized antenna, and for the two cases in which the designs of the inset-fed length are performed using the techniques presented in 6 and 7. The impedance matching is done by recesses (inset-fed), which is optimized to minimize the return loss (RL). The excitation of this structure is done using a microstrip line (L0). Inset Feed Patch Antenna Calculator Software And TheThe antennas are designed using the package Ansoft DesignTM software and the new structures optimized with GA are simulated, measured and compared with the same patch antenna but with the lengths of the inset-fed (y0) calculated by well known models available in the literature.
