Are PMOs really that momentous for public authorities?

International Journal of Information Systems and Project Management, 2022
Project management offices (PMOs) are frequently referred to as necessary, or even indispensable, for carrying out projects in multi-project settings, which often occur in public authorities’ Information Technology (IT) projects; particularly in times ...

Dual‐band single‐layer substrate‐integrated waveguide filtering antennas with independently controllable bands

IET Microwaves, Antennas & Propagation
A novel design method of dual‐band single‐layer substrate‐integrated waveguide (SIW) filtering antennas with independently controllable bands is proposed in this paper. The basic two‐pole dual‐band filtering antenna is proposed by a dual‐mode rectangular

Substrate-integrated-waveguide cavity-backed circularly polarized antenna with enhanced bandwidth and gain

ETRI Journal
We propose a method for increasing the bandwidth of a substrateintegrated-waveguide (SIW) cavity-backed antenna with taper-based microstrip SIW transition feeding. For radio transmission, a circular slot is etched on top of the SIW cavity.
