A research on Antenna design and simulation is a emerging area among researchers. Antenna is a basic element for wireless communication. There are various shaps and types of antenna, which uses in different allpication. Now a days Microstrip patch anteena is very useful in advance electronics devices applications. This paper focused on study based various types of microstrip antenna. Return loss, VSWR, bandwidth, resonant frequency and gain is key parameters to judge antenna performance. Good value of return loss is less than -10dB. Considerable range of VSWR is 1-2. CST microwave studio is a advance software to design and simulation of all types of antenna, filter etc.
Microstrip patch antenna (MPA) plays key role in the wireless communication. The research is continuing going to design and optimization of the antenna for various advance application such as 5G and IOT. Artificial intelligence based techniques such as machine learning is also capable to optimize the parameter values and make prediction model based on the given dataset. This research paper shows the machine learning based techniques to optimize the microstrip patch antenna parameters with the performance improvement in terms of accuracy, Mean Squared Error, and Mean Absolute Error. The antenna optimization process may be greatly accelerated using this data-driven simulation technique. Additionally, the advantages of evolutionary learning and dimensionality reduction methods in antenna performance analysis are discussed. To analyze the antenna bandwidth and improve the performance parameters is the main concern of this work.
A body wearable antenna (BWA) is a hotly research issue for the examination. In this paper different kind of receiving antennas are displayed which are as of now accessible in writing. A BWA is a material receiving antenna, which is adaptable and comfort. At some point it isn't important that space accessible for mounting the receiving antenna is level, so radio antenna ought not to change its qualities amid twisting conditions. Save specialists for the most part work in such a domain which is disjoined by multipath, which cause the blurring of got flag. So to keep away from such kind of issue a multi energized reception apparatus may require. Besides when receiving antenna is put over the human body, because of bidirectional properties of radio antenna in reverse radiation may hurt the wearer's body. So to minimize such radiations EBG (Electromagnetic band gap) structures are utilized.
This work describes a 12-bit pipeline ADC (Analog-toDigital Converter) for CMOS (Complementary Metal Oxide Semiconductor) that is implemented in a TSMC 0.18μm CMOS process. The proposed ADC utilizes the Threshold Inverter Quantization (TIQ) technique that uses two cascaded CMOS inverters as a comparator. the TIQ flash ADC achieves high speed, small size, low power consumption, and low voltage operation compared to other ADCs The sample and hold circuit have high Sampling rate. This Design is implemented and Fabricated in TSMC 0.18μm CMOS verified on the LT SPICE in 0.18µm Technology.
