Ka-Band Lightweight High-Efficiency Wideband 3D Printed Reflector Antenna

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...

Printed wideband CPW-fed slot antenna with high polarization purity

This paper introduces a novel compact wideband CPWfed slot antenna comprising of an E-shaped patch that is excited with a trident shaped feed-line structure. The antenna design exhibits a very wide operating bandwidth of over 168% with S11 < −10 dB in the frequency range 1.6 to 18.9GHz. The antenna’s radiation characteristics are stable across this wide bandwidth. The proposed antenna exhibits ...

Dual-band and Wideband Design of a Printed Dipole Antenna Integrated with Dual-band Balun

A dual-band printed dipole antenna with integrated balun feed is given in this paper. First, the fork-shaped slot is etched on the arms of the printed dipole antenna to achieve the dual-band operation with resonances at WLAN bands. The radiating element without balun is optimized and operates at 2.4 GHz (2180–2750MHz) and 5.2GHz (5040 MHz–5480MHz) where return loss is less than −10 dB. In order...
