Abstract
A new microstrip structure for realization of wideband phase shifter has been designed and fabricated. The proposed design uses edge-coupled semi-elliptical structure and an elliptical defected ground plane to increase the coupling coefficient and operating bandwidth. Simulation performed using CST Microwave Studio and measured results confirm the good performance of the proposed design. The phase deviation is better than ±4º, insertion loss less than 0.6dB and return loss better than 10dB over a wide frequency range. The achievable bandwidth is more than 2.3 : 1.
