Miniaturized microwave components have drawn increased attention due to the size shrinking of the modern communication systems. This dissertation proposes two approaches to address this problem by reducing the size of the RF components and the antennas. First, miniaturized substrate integrated waveguide components are introduced and developed by using the metamaterial concept. Traditional waveguide components have excellent performance but with a bulky size due to the above-cutoff frequency operation. We demonstrate that by loading the metamaterial elements, the rectangular waveguide can be operated well below the cutoff frequency while maintaining good performance.

A waveguide is a structure that guides waves, such as electromagnetic waves or sound , with minimal loss of energy by restricting the transmission of energy to one direction. Without the physical constraint of a waveguide, wave amplitudes decrease according to the inverse square law as they expand into three dimensional space. There are different types of waveguides for different types of waves. The original and most common [1] meaning is a hollow conductive metal pipe used to carry high frequency radio waves , particularly microwaves. Dielectric waveguides are used at higher radio frequencies, and transparent dielectric waveguides and optical fibers serve as waveguides for light.

These units comprise a length of waveguide into which is inserted a power absorber designed to absorb the microwave energy with minimum reflected power. The heat generated by the absorption is dissipated by means of heat sinks and fan assisted forced air, where necessary. Albacom Microwave low power terminations are constructed using selected drwan tube and precision tapered absorbing elements to achieve low VSWR performance. Low Power Terminations. Albacom Microwave range of medium and high power terminations are designed specifically to meet the stringent requirements of the commercial and military satellite uplink markets.

SPINNER millimeter wave testing components give you unprecedented flexibility in creating millimeter wave testing environments. Our solutions are mechanically extremely flexible and uncompromisingly good in technical terms. The number of applications in the millimeter wave range is growing steadily, and with them the need for appropriate testing equipment.


Student thesis : Master. Abstract To realize next generation mm-wave wireless systems it is vitally important to utilize cost effective manufacturing technologies and to develop low-loss waveguides and transmission lines. Furthermore, being able to interface system components through contactless transitions is another key objective. In fact, recently, optical connections between chips through fibers is being researched heavily in the photonics science field, while the quasi-optical connection as proposed in this MSc thesis between chips through waveguides presents a similar breakthrough, albeit in the mm-wave range.

Rectangular Cavities. Microwave Circuits Microwave engineering Notes - MWE pdf notes. This reference book is designed to be used as a manual to assist in the solving of design problems. I am here sharing the handwritten pdf notes for Microwave engineering as per the syllabus of electronics branch engineering students. There are several frequency ranges assigned to microwave systems, all of which are in the Giga Hertz GHz range and the wavelength in the millimeter range. We will discuss these in more detail later in the chapter.
