PROJECT TITLE :
Electronically Steerable and Fixed-Beam Frequency-Tunable Planar Traveling-Wave Antenna
The design of an electronically steerable wideband planar traveling-wave antenna is presented. The proposed antenna contains a very easy structure based mostly on a microstrip line loaded with several radiating components and part shifters between them. The phase shifters are primarily based on tunable capacitances, so as to perform an eternal section shift between the radiating parts and management the main beam direction. The radiating elements are complementary strip slots that have a very broad impedance bandwidth, therefore permitting the antenna to own 2 different modes of operation: maintaining the main lobe direction over a significant bandwidth, 1.seventy one–two.17 GHz, and performing a main beam scanning over this bandwidth with a most angle range of to forty five° at a pair of GHz.
