Design and Analysis of Microwave Power Dividers/Combiners

Abstract

Most of recent systems require power dividers/combiners that have compact size, low profile and high efficiency as well as capability to be embedded in integrated circuits. Recently, the rapid progress in modern communication systems requires multi-band transceivers as a demand of integrating more than one standard communication system into a single system. Therefore, multi-band microwave power dividers/combiners play an important role in modern communication systems such as Global System for Mobile Communications (GSM), Universal Mobile Telecommunication Systems (UMTS) Bluetooth, IEEE 802.11 Wireless Local Area Networks (WLAN), and IEEE 802.16 Worldwide Interoperability for Microwave Access (WiMax) systems. As a result, the main purpose of this thesis is to study, develop and implement a quad-band power divider/combiner with small size, simple planar structure, and well organized design methodology. Another objective is to propose novel ideas as well as design guidelines to overcome related constraints and challenges.
