Examining 3D Printed Antennas For Space Based Applications
… build conformal designs. The idea of 3D printing antennas is not new and has been researched in recent years. However the possibility of using 3D printed antennas for space applications has been researched very little. The harsh space environment makes material selection an important factor in …

Model and design of small compact dielectric resonator and printed antennas for wireless communications applications. Model and simulation of dialectric resonator (DR) and printed antennas for wireless applications; investigations of dual band and wideband responses including antenna radiation performance and antenna design optimization using parametric studies
… ceramic materials, this may be very low. These antennas are typically of small size, with a high radiation efficiency, often above 95%; they deliver wide bandwidths, and possess a high power handling capability. The principal objectives of this thesis are to investigate and design DRA for low …

Investigation into the design of ultra-wideband (UWB) and multi-band antennas
… on the family of square plate monopole (SPM) antennas for UWB applications. The family of square plate monopole (SPM) UWB antennas yields quite attractive features, viz.: ease of fabrication and freedom of dielectric material selection. Next, we considered the use of coplanar waveguide (CPW) …

Design and Implementation of Reconfigurable and MIMO Antennas for Future Heterogeneous Wireless Systems
… equipment poses a key design challenge, as most antennas often suffer from bandwidth limitations and restricted frequency rarge. Onekey approach to overcome this problem without significantly affecting the antenna size is to apply antenna tuneability and reconfigurability. This is achieved by …

Wireless Coupled Feed Structure for Additively Manufactured Conformal Antennas
… electromagnetic devices that can be conformally printed directly onto 3D surfaces using conductive inks and dielectric pastes. Instance, the traditional antenna radomes that had the purpose of protecting the antenna on its inside can now become the antenna itself. With the components on the …
