A 3D Printed Ka-Band High-Efficiency Wide-Slit Antenna Array for High-Power Microwave Applications

High Gain Planar Antenna Structures for Ka-band Applications

Ka Band Transmit Antenna Array

Active antenna arrays working at higher frequencies result in higher packaging densities. The antenna array under consideration operates at about 30 GHz and will be installed in an aircraft. Commercially available power amplifiers at these frequencies have an efficiency of typically 20 %, which results in high amounts of dissipated heat for the required high radiated power. The dissipated power...

A Small Printed Quadrifilar Helical Antenna for BGAN/GPS Applications

This paper presents an element of a 2×2-element array antenna for Inmarsat BGAN/GPS applications. The element is an axial mode printed quadrifilar helical antenna that has been integrated with a compact feed network to provide sequential phase rotation for circular polarization (CP) radiation. The novel integrated lumped-element feed network is designed to provide a balanced RF power to the fou...

Ka-Band Triangular Patch Antenna on Micromachined High-k Substrate

This paper reports the design of a Ka-band Equilateral triangular patch antenna (ETPA) fabricated using postCMOS and post-MMIC compatible process technology. The antenna uses an air-cavity underneath the patch radiator that is supported on thin dielectric membrane. The antenna structure was analysed and optimised using the finite element method (FEM) based Agilent High Frequency Structure Simul...

Design and Analysis of Miniaturized Multiband High Frequency Antenna for K and Ka Band Applications

This paper proposes the design and analysis of co-axial continuous transverse stub multiband antenna (CCTS) for multiple high frequency Applications. Coaxial continuous transverse stub antenna is used to operate on multiple frequency bands with small size and low cost. This proposed antenna consists of two stubs, arranged longitudinally to form a waveguide skeleton like structure. The advantage...
