In this letter, a microstrip dual-band band-pass crossover is proposed. By reducing the number of inner open stubs, miniaturization of a window-shaped crossover without reducing bandwidth can be achieved. An electromagnetic simulation and measurem...

In this paper, we compare the performance of activation functions on a deep image prior. The activation functions considered here are the standard rectified linear unit (ReLU), leaky rectified linear unit (Leaky ReLU), and the randomized leaky rec...

This paper presents a miniaturized branch-line coupler with harmonic suppression. By using a combination of a 45° open stub and a 45° short stub instead of using a 90° short stub, we can achieve harmonic suppression while maintaining good RF bandw...
