A Scalable Ka-Band 1024-Element Transmit Dual-Circularly-Polarized Planar Phased Array for SATCOM Application

Design of High Performance Circularly Polarized Radiating Element for Phased Array Antenna for Satcom on the Move

The paper describes the design, development, and characterization of a circularly polarized, wide beam radiating element for Electronically Steered Phased Array Antenna (ESPAA) for satellite communication (Satcom) on the move application at S-Band frequency. A corner truncated microstrip patch etched on Rogers TMM4 dielectric material placed on a rohacell filled the metallic cavity is proposed ...

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...

Miniaturized Phase-Shifters for Ka-Band Phased Array Antennas

Realizing robust and stable two-way links between the mobile users and the satellite is an extremely challenging RF/Microwave engineering problem. Low cost and low pro le phased array is considered as the best solution for this problem. High performance low cost and miniaturized variable phase shifter is a key enabling technology for such complex smart phased array antenna system. This thesis a...

A Dual-Band Circularly-Polarized Patch Antenna with a Novel Asymmetric Slot for WiMAX Application

A compact design of a circularly-polarized (CP) microstrip antenna to achieve dual-band behavior for WiMAX applications is presented. A single-layered feed is used to excite a single square patch integrated with a novel asymmetrical slot and two different truncated corners to achieve CP polarization in both bands. Besides its structural simplicity, ease of fabrication and low cost, the proposed...
