GaN transistors the main active high-power element in this amplifier designs for high efficiency. Keysight Advance Design System (ADS) simulation tool is used to design and optimize the input and output matching along with transient & EM simulation of power amplifier. The 3-stage amplifier has been designed using two driver stages and one power stage amplifier. The bias sequencing circuit for GaN is designed using P-channel, N-channel MOSFETs and AND gates. The amplifier has provision of reverse polarity protection and switching on/off by digital controls. This amplifier works with single power supply which can range from 8V-60V and its output can be switched between two antenna ports. With optimized matching networks, more than 4-watt output power, power gain of 15 dB and power added efficiency (PAE) of more than 50% are obtained at carrier frequency of 1200 MHz and band width of 100 MHz of main power stage. The isolation between the two antenna ports is more than 50 db. The amplifier has been designed with thermal compensation for power output of more than 4 watt in the temperature range of - 20°C to +55°C. The hardware realized using mixed four-layer PCB with the total thickness of 1.6 mm on Rogers 4350B and FR-4substrate. The top Layer 20 mil Rogers 4350B is used for RF routing. Components are populated on both side of the PCB due to size constraint. The SWaP optimized amplifier has been realized in mechanical housing with the size of 124 mm x 86 mm x 31.5 mm (LxWxH) and weight of 480 gm with extra mounting studs for fitment.","PeriodicalId":228280,"journal":{"name":"2023 First International Conference on Microwave, Antenna and Communication (MAC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117042220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To achieve these requirements, high gain antenna operating at low frequency ranges with considerable bandwidth is needed. As, wider bandwidth improves the range resolution and high gain improves the range. Therefore, the L-band antenna is a suitable choice for further investigation and research. While designing the antenna, it is observed that antenna size is one of the important constraints for the development of imaging system. Therefore, this research article examines the effect of gain improvement for a dielectric superstrate and slot in the microstrip patch antenna that can be efficiently used for microwave imaging applications. The proposed design of antenna consists of simple geometry. However, lower gain, low radiation efficiency, and narrow bandwidth are the key digression factors associated with microstrip patch antenna. To overcome these limitations, the use of superstrate with slot in patch antenna are studied here. A dual layer superstrate approach is utilized to achieve improved gain along with high F/B ratio in this paper. The development stages of the proposed antenna are discussed and evaluated. Furthermore, parametric analysis is also conducted and reported for better observations.","PeriodicalId":228280,"journal":{"name":"2023 First International Conference on Microwave, Antenna and Communication (MAC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123947623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bomb disposal operations provide a number of difficulties, including significant hazards to weapon designers, disposal technicians, and mission controllers. A typical explosive ordnance disposal mission will begin with a remote-controlled robot surveying the area, in order to determine whether the explosive can be remotely deactivated. At times, a person who is skilled in bomb disposal is required to deactivate the device. The specialist who detonates the device will do so by donning a defensive suit and helmet, grabbing a toolbox of supplies, and moving around 100 meters to the location. It could be required to climb stairs, squeeze through a small space, or even lay down to reach the bomb's location in order to complete the task. To ease this task we designed the device, also comes with a camera that will enable viewing of both daytime and night time recordings enabled with android application is used to control the entire system. The improved vehicle is constructed from PVC pipes connected to a nearby connection of a rocking buggy to provide sloping security. Spying robot is controlled via the web using the Blynk application. Spying robot has Zigbee connectivity, Meal and gas sensors operate independently and send SMS alerts using the GSM module, along with GPS coordinates.","PeriodicalId":228280,"journal":{"name":"2023 First International Conference on Microwave, Antenna and Communication (MAC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117275421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed SIW based antenna operates at 5.3 GHz ISM band for wireless application. The basic cavity is obtained using a substrate integrated waveguide technology, in which copper filled cylindrical vias are embedded between top and bottom layer of cavity through substrate to convert non planar structure into a single PCB layer form. The entire structure with feeding component is incorporated in the same plane of PCB. The antenna is optimized using software HFSS. Besides having a conventional slot, in the proposed antenna, two rectangular slots having different lengths and angles but same widths on the top layer of the SIW cavity are etched from cavity and excited by a 50-ohm micro strip line inset feed. By properly optimizing the overall geometry antenna shows a gain of 6.53 dBi at frequency of 5.3 GHz. Structure shows stable bidirectional radiation pattern, efficiency is 90.6 % and VSWR is less than 2 throughout the desirable frequency band.
