Port-a-cath is a widely used device in patients with long-term venous access demand such as frequent or continuous administration of medications such as Enzyme Replacement Therapy (ERT), chemotherapy delivery, blood transfusions, blood products, and fluids. Patients with Lysosomal Storage Diseases (LSDs) often require recurrent courses of ERT. We reviewed our experience of using port-a-caths in...

The use of multi-antenna systems with multiple-input multiple-output (MIMO) technology will play a key role in providing high spectrum efficiency for next generation mobile communication systems. This thesis offers valuable insights on the design of compact multi-antennas for efficient MIMO communications. In the course of the thesis work, several novel six-port antenna designs have been propos...

In this paper a design of millimeter-wave six-port device for LTCC (Low Temperature Cofired Ceramic) technology is presented. Furthermore, problems with implementation the project taking into account requirements are discussed.

This paper presents design and analysis of two different Ultra Wide band (UWB) six-port correlators for transmitter and receiver applications. The two designs analyzed and compared in terms of transmission parameters, relative bandwidth and occupied area. On one side, design of microwave components for multiGiga Hertz bandwidth is a non-trivial challenge. Meeting such challenging performance sp...

This paper presents two new structures for six-port reflectometers with very large operating bandwidths of more than three decades, using a combination of lumped reflectors and transmission lines. Circuits working over a range of 2 MHz to 1300 MHz and 2 MHz to 2200 MHz have been built using inexpensive passive surface mount elements and Schottky detector diodes. Comparing results obtained from ...
