Abstract
Pinching-antenna systems enable highly flexible deployment by dynamically adjusting antenna positions along a dielectric waveguide. In this work, we investigate their performance for practical channels with in-waveguide attenuation. We first introduce a channel model that captures both in-waveguide and free-space propagation, based on which the optimal antenna placement is derived. Building on this result, we further characterize the average data rate loss incurred when in-waveguide attenuation is ignored. Our analytical results show that in-waveguide attenuation can be safely neglected without causing significant performance degradation, provided that the communication region is not excessively large. Simulation results further demonstrate the performance gains of pinching-antenna systems compared with conventional fixed-antenna baselines.
