1. Introduction

•  Background
Ø  As consequence of the rapid development in wireless communication market, various devices need to integrate wireless standards. Demand on wireless devices to support these multi-standard operations with [2] §  Low insertion loss §  sharp selectivity §  Proper compact size §  Low cost

Ø  Band-pass filters
§  primarily used in wireless transmitters and receivers §  limit the bandwidth of the output signal to the minimum necessary to convey data at the desired speed and in the desired form §  also used in bio-photonic, medical analytical, chemical, pharmaceutical area etc

Ø  Power dividers
§  passive microwave components used for power division §  Divide input signal into two signals of lesser power. The coupler may be a three port component with or without loss §  usually of the equal-division type, which is 3dB, but unequal power division ratio is also possible [4] 3

1. Introduction

•  Motivation
Ø  Why 60GHz
§  First published by Indian physicist J.C. Bose 1895 §  In 1947, US physicist J.H. Van Vleck observed that the oxygen molecule absorbs electromagnetic more energy at 60-GHz than at other frequencies [6] §  Mainly driven by military and space applications 1960s to 1980s [7] §  From mid-1990s, interest in fixed broadband wireless access for last mile connectivity advanced 60-GHz radio technology [8]

Ø  Why SIW filter and power divider
§  Conventional technologies: either not able to present required performance or too expensive §  SIW: as an attractive technology for low cost, high Q-factor, relatively high power, and high density integration of microwave and millimeter-wave components and sub-systems [10]-[12]. §  SIW filters have a low in-band insertion loss and a wide stopband performance. §  SIW power dividers not only achieve the small size but also realize transmitting a defined amount of the electromagnetic to another two ports. 4

2. Literature Review

•  Transmission Line
Ø  A device designed to carry electric energy from one to another, is used to transfer the output radio frequency energy of a transmitter to a receiver [15].

•  Microstrip Line
Ø  One of the most popular types of the electrical TLs Ø  convey microwave-frequency signals Ø  support a good quasi-TEM wave Ø  In practical applications,...
