A Ka-Band High-Efficiency Transparent Reflectarray Antenna Integrated With Solar Cells

Reflectarray for K/ka-band Terminal Antenna

Different satellite systems have been defined to provide broadband communications and internet access in remote geographical areas in Ka band (20-30 GHz) [1-2], being the up-link at 30 GHz and the down-link at 20 GHz. Costeffective antennas are required for fixed and portable terminals in Ka-band. Conventional reflectors are a preferred option to maintain reduced costs. However, the different r...

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...

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...
