HIS is a preferred substrate for low-profile antenna design, owing to its unique boundary conditions. Such substrates permit radiating elements to be printed on them without any disturbance in the radiation characteristics. Moreover HIS provides improved impedance matching, enhanced bandwidth, and increased broadside directivity owing to total reflection from the reactive surface and high input impedance. This book considers different configurations of HIS for array design on planar and non-planar high-impedance surfaces. Results are presented for cylindrical dipole, printed dipole, and folded dipole over single- and double-layered square-patch-based HIS and dogbone-based HIS. The performance of antenna arrays is analyzed in terms of performance parameters such as return loss and radiation pattern. The design presented shows acceptable return loss and mainlobe gain of radiation pattern. This book provides an insight to EM design and analysis of conformal arrays. This book serves as an introduction for beginners in the design and analysis of HIS-based antenna arrays. It includes pictorial description of both planar and non-planar array design and the detailed discussion of the performance analysis of HIS-based planar and non-planar antenna array. It will prove useful to researchers and professionals, alike.\u003c\/p\u003e","brand":"WoB","offers":[{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":49554922340625,"sku":"GOR001401788","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ GOOD \/ SBYB","offer_id":50233948143889,"sku":"CIN0953254208G","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ WELL_READ \/ SBYB","offer_id":50374796280081,"sku":"CIN0953254208A","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":50374801064209,"sku":"CIN0953254208VG","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ GOOD \/ INTERNAL","offer_id":50751286477073,"sku":"GOR001945221","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0953254208.jpg?v=1751108638"},{"product_id":"my-last-heartbeat-book-elizabeth-hayden-9781665752800","title":"My Last Heartbeat","description":"Safornia was born in the late 1930s with a rare birth defect. She was born with her heart and brain on the outside of her body. At the time, it was the second known case in the world. The chances of her survival were less than slim, and her family lived in fear every day of losing their sweet, beautiful girl. During an era of limited medical technology and experience, long term care for baby Safornia was practically inconceivable. The rarity of her condition raised skepticism amongst the public as news of Safornia began to spread. Strangely, her rare birth defect incited fear. The verbal abuse and physical harassment at the hands of violent crowds left emotional scars that would never heal. My Last Heartbeat is the true story of author Elizabeth Hayden's mother's struggles to shield her baby from the disrespectful curiosity of an unloving world. Even in death, there was no peace for tiny Safornia, as after she passed, graves all across Washington DC were disturbed in an effort to see the rare site. The child could not rest in life or death . but a mother's love never dies.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52125120037137,"sku":"NLS9781665752800","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9781665752800.jpg?v=1757462382"}],"url":"https:\/\/www.worldofbooks.com\/collections\/author-books-by-elizabeth-hayden.oembed","provider":"World of Books ","version":"1.0","type":"link"}
