Microstrip Filters for RF/Microwave Applications, 2/e (Hardcover) (書側有些許黴斑)

The first edition of “Microstrip Filters for RF/Microwave Applications” was published in 2001. Over the years the book has been well received and is used extensively in both academia and industry by microwave researchers and engineers. From its inception as a manuscript the book is almost 8 years old. While the fundamentals of filter circuits have not changed, further innovations in filter realizations and other applications have occurred with changes in the technology and use of new fabrication processes, such as the recent advances in RF MEMS and ferroelectric films for tunable filters; the use of liquid crystal polymer (LCP) substrates for multilayer circuits, as well as the new filters for dual-band, multi-band and ultra wideband (UWB) applications.

Although the microstrip filter remains as the main transmission line medium for these new developments, there has been a new trend of using combined planar transmission line structures such as co-planar waveguide (CPW) and slotted ground structures for novel physical implementations beyond the single layer in order to achieve filter miniaturization and better performance.

Also, over the years, practitioners have suggested topics that should be added for completeness, or deleted in some cases, as they were not very useful in practice.

In view of the above, the authors are proposing a revised version of the “Microstrip Filters for RF/Microwave Applications” text and a slightly changed book title of “Planar Filters for RF/Microwave Applications” to reflect the aforementioned trends in the revised book.

《微帶濾波器在射頻/微波應用中的應用》第一版於2001年出版。多年來，這本書受到廣泛好評，被射頻研究人員和工程師在學術界和工業界廣泛使用。從手稿開始，這本書已經有近8年的歷史。儘管濾波器電路的基礎原理沒有改變，但隨著技術的變化和新的製造工藝的應用，如最近射頻微機電系統（RF MEMS）和可調濾波器的鐵電薄膜的進展，以及液晶聚合物（LCP）基板用於多層電路，以及用於雙頻、多頻和超寬頻（UWB）應用的新型濾波器，濾波器的實現和其他應用也有進一步的創新。

儘管微帶濾波器仍然是這些新發展的主要傳輸線介質，但近年來出現了一種新趨勢，即使用結合的平面傳輸線結構，如共平面波導（CPW）和開槽接地結構，以實現超越單層的新型物理實現，以實現濾波器的微型化和更好的性能。

此外，多年來，從業人員提出了應該添加的主題，以便完整，或在某些情況下刪除，因為它們在實踐中並不是非常有用。

基於上述原因，作者們提出了《射頻/微波應用的平面濾波器》修訂版的提案，並稍微修改了書名為《平面濾波器在射頻/微波應用中的應用》，以反映修訂版中所述的趨勢。
