Investigating the effects of control lines on a frequency reconfigurable patch antenna Ajit M. Yadav Chinthana Panagamuwa Rob Seager 2134/8099 https://repository.lboro.ac.uk/articles/conference_contribution/Investigating_the_effects_of_control_lines_on_a_frequency_reconfigurable_patch_antenna/9554423 The objective of the paper is to investigate the effects of metallic control lines on a frequency reconfigurable patch antenna. The designed antenna resonates at 3 different frequencies in range of 3-4GHz. Simulation and measurement results of return loss with and without control lines are presented. We have also discussed the challenges of implementing the bias lines. 2011-02-21 14:26:16 Reconfigurable antennas Electronic switching PIN diode Bias lines Mechanical Engineering not elsewhere classified
