Abstract

Objectives: Design & Simulation of Sierpinski Carpet Antenna utilizes Two Feeding Method. Method: Sierpinski carpet antenna is presented in this paper. In this planned structure firstly we take FR4 substrate with 4.4 permittivity and 0.001 loss tangent. Now taking thickness 1.6 mm we cut the square on a rectangular patch having 10x10mm length and width individually. After that we perform iteration up to three. Than after these three iteration we have to simulate the antenna using IE3D software. In this we use two feeding TL feed and P feed. By implementing these parameters of antenna design a higher bandwidth and gain is achieved. At last the antenna is simulated on IE3D having frequency range of 0-4 GHz for transmission line feed and 8-16 GHz for probe feed. Findings: Now using two feeding we compare the results of each iteration and find the parameters. Return loss and the bandwidth of Antenna is increment. Table 1 demonstrates the outcome of MSPA where the return loss of Antenna in first iteration is - 18.3977, - 18.3832 in second iteration and - 19.0005 in third iteration. We focus at the bandwidth, return loss, and impedance parameters of Antenna. With the expansion in iteration, the operating frequency of 1.3333GHz. The return loss of PB feed for every iteration is - 15.45, 17.58, 19.501 dB separately which is step by step expanded. Table 2 additionally demonstrates the VSWR and bandwidth of every iteration at same frequency for various. In three iteration, the bandwidth is likewise preferable in transmission line sustain over test encourage. Application: The optimized antenna is thin profile, light weight, inexpensive easily fabricated and compact. That’s why; proposed antenna can be used for various wireless applications like WLAN, Bluetooth, and Wi-Fi etc.

Abstract

Objectives: To simulate a unique design with T slotted with two different feeding methods. Method: In this paper we use IE3D software in which we select mgrid with basic parameters 0.025 mgrid size and FR4 substrate 4.4 having thickness 1.6 mm and loss tangent 0.001. Then select a rectangular patch from entity with 10 mm length and 10 mm width and cut 3-T slots alternately. After complete our design we fed it 50 ohm to with 10 mm feeding for transmission line feed and (0, 3.5) its x and y value for probe feed and then operate it at different frequencies. Findings: The simulated results fetched at the frequency of 0-4, 8-16 GHz for TL feed and PB feed individually. The RL of TL feeding is -20.696 dB resonant at 1.32492 GHz and -28.27 dB for PB feeding resonant at 13.33 GHz. After comparing the outcomes for both feeding techniques, we conclude that the result of antenna in transmission line feed is more negative than probe feeding as shown in Table 1. The BW of desired antenna is 44.6% for TL feed and 9.8% for PB feed which is appropriate for wideband. As the notch frequency falls in SHF range so the antenna is right for many commercial as well as for typical services like WLAN, Satellite links. Application: This antenna is useful in WLAN, satellite links etc.

Abstract

Objectives: In this paper our focal intention is propose a unique design with crown square shape fractal antenna and activate it at multi-frequencies using two feeding methods and evaluate their results. Method: We use three iteration methods, firstly select mgrid from IE3D Zealand software, after creating a new file we select basic parameters 0.025 mgrid size, 1.6mm thickness of FR4 having value 4.4 and loss tangent 0.001. Then select rectangular shape from entity with 10-10 mm length and width and using crown shape to cut slots in rectangular patch and complete our design. We use 10 mm feeding length fed with 50 Ohm in TL Feed and in PB Feed we use (1.8,5) x-y points and simulate it at range of 0-5 GHz and 8-16 GHz frequency in that order. Findings: By using all steps mentioned above we complete our design and simulate it using two different feeding techniques at different frequencies and compare their results. In Transmission line feed our antenna operates at 1.11111 GHz frequency and for probe feed it is 9.77778 GHz and after this we calculate all of its parameters. As shown in Table 1, TL feed return loss is -25.1832, -25.0821, and 24.6284 whereas in PB feed is -16.7513, -18.6701, and 20.1873 in three iterations respectively. Similarly Bandwidth is 71.17%, 71.17%, 70.2% and 9%, 10.03%, 10.25% and VSWR is 1.11654, 1.11789, 1.1247 and 1.34016,1.26384,1.21697 respectively .The value of impedance is 50.6254, 50.6203, 50.2958 and 50.83, 50.16, 49.15 in iteration 1st, 2nd and 3rd individually. As our design is able to operate at different frequencies so we select particular frequency and compare their results by different feeding methods with same design so that it may be useful at different applications. Application: As it is operate at multi-frequency with high bandwidth so it is useful in Telemedicine, RFID, Satellites communication, GPS etc.
