“…These resonators can be considered as metamaterial with Epsilon Near Zero Index (ENZI) [1], where the phase velocity of propagating electromagnetic waves tends to infinity in ENZI ing the aperture efficiency of the array system. Moreover, it can be noticed that at lower frequency of the band (i.e., 4 GHz) the bigger sized dipoles have more contribution in the overall radiation.…”

Three scenarios of high gain bow-tie based antenna array systems are introduced and investigated in this paper. The proposed designs are intended for integration as Tx/Rx antennas in C-band communication systems. Wide operating bandwidth and consistent radiation characteristics over the frequency range from 4 GHz to 5 GHz are defined for the three configurations. A two-stage Wilkinson power divider provides the feed mechanism for the proposed array. The initial structure has four radiating elements, each incorporating seven bow-tie dipoles arranged in a printed Log-Periodic Directional Array (PLPDA) configuration. The gain of the second and third designs is improved by adding resonators in front of the array elements. Furthermore, the second design features triangular-shaped resonators, while the third design employs H-shaped resonators. The designs are simulated and optimized using HFSS and CSTMWS software, and subsequently, they are fabricated using the photolithography technique. The initial design demonstrates an experimental bandwidth from 3.7 GHz to 5.1 GHz and achieves a measured gain of 13.8 dBi at 4.7 GHz. The second and third configurations operate in the frequency bands of 4.3 GHz to 5.3 GHz and 3.7 GHz to 5 GHz, respectively, exhibiting measured gains of 14.1 dBi and 15 dBi. The overall dimensions of the proposed arrays are kept within reasonable limits, with the first array being 2.51λ × 2.74λ, the second being 2.09λ × 2.82λ, and the third being 2.51λ × 2.97λ. The three array designs can be considered as good candidates for C-band communication applications.

This paper introduces a novel RF phase shifter design that operates at constant phase shift over operation frequency range. The proposed phase shifter utilizes the conventional reflective-type phase shifter which is inherently frequency-dependent. The introduced reflective-type phase shifter design is integrated with an adaptive control circuit that varies the required DC voltage as a function of the frequency. Thus, the phase shift will be relatively constant throughout the frequency of operation compared to the conventional frequency-dependent reflective-type phase shifter. The phase shifter is designed to operate at 90 • and is shown to maintain that phase shift with around 15 • compared to the conventional design where the phase shift varies by more than 60 • at the same bandwidth. The proposed design, including the adaptive controlled circuit, is fabricated, and the measured data agree with simulations.
