In this article the use of cross monopole antennas is discussed. These antennas are known for their wide impedance bandwidth and good omni-directional radiation pattern. A novel dual-band-rejected design for cross semi-elliptic monopole antenna is proposed and experimentally studied. The proposed antenna consists of an ultra-wideband cross semi-elliptic monopole...

1. Introduction As wireless carriers start to move towards 4G mobile technology, it is placing huge demands on their backhaul infrastructure. The multiple, high-bandwidth, quality-sensitive services that carriers have planned for 4G technology requires an infrastructure that is packet-based, scalable and resilient, as well as cost-effective to install, operate...

I. INTRODUCTION The integrity of shielding enclosures is compromised by apertures and seams required for heat dissipation, cable penetration, and modular construction, among other possibilities [1]. These perforations allow energy to be radiated to the external environment from interior electronics, or energy coupled from the exterior to interfere with...
