“…Thus, the phase arrays with compacted and low-cost performances are critical requirements in the communication domain. The planar beam steering arrays presenting shunt-arrays [17][18][19][20][21][22][23][24] and serial-fed arrays [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] forms with low profile are proposed in recent years. The shunt-fed arrays resemble the amount of the power dividers which leads to the complexity and large-energy loss in the system [17][18][19][20][21][22][23][24].…”

A 1-bit phase reconfigurable fixed-frequency beam steering leaky-wave antenna (FBSLWA) with wide-angle steering is proposed in this paper. By controlling two p-i-n diodes on the branches of the element, a stable 180° phase difference is realized. Moreover, the open stop-band effect at the broadside radiation is suppressed by reducing the reflection coefficients of the element. The proposed FBSLWA can achieve wide-angle steering within a frequency bandwidth of 10.4 GHz to 11.8 GHz. As for the measured results, they show that the achievable beam steering ranges of the FBSLWA at 10.4 GHz, 11.0 GHz, and 11.8 GHz are -61° to +59°, -64° to +71°, and -62° to +58° respectively, with measured peak gains of 12.1 dBi, 13.9 dBi, and 11.7 dBi.

“…Consequently, the serial-fed arrays have shorter transmission paths and lower losses in the transmission line. Additionally, serial-fed arrays have a simpler structure that can reduce the complexity of array design [40,41,45,46].…”

This study provides the design and demonstration of a Ku/K band horn‐fed linear polarization (LP) to circular polarization (CP) converter using a reflectarray antenna based on the holographic technique and the generalized law of total reflection without any iterative algorithms. The proposed hologram performs wide‐range frequency beam scanning with minimum gain losses and cross‐polarization levels. It comprises 2,500 diagonal slotted octagonal subwavelength metasurfaces with a periodicity of 0.266λ0 = 4 mm at 20 GHz as the center frequency. Two equations are defined to compute Y11 of the proposed unit cell regarding its dimensions for TE(0,0) and TM(0,0) Floquet modes. They significantly simplify the coding procedure and reduce the computational time for synthesizing the hologram. The antenna is simulated using the CST software from 14 to 25 GHz. As a confirmation, a prototype is manufactured and measured at 16, 18, 20, 22, and 24 GHz to verify its performance. The simulated and measured results are well‐matched. The presented hologram achieves 40% 1.8‐dB axial ratio (AR) bandwidth (16–25 GHz), 40% 3.3‐dB gain bandwidth (16–24 GHz), and above 30% 2‐dB gain bandwidth (16–22 GHz). Moreover, the antenna can perform beam scanning from 42° to 24° by changing the frequency from 16 to 24 GHz with peak gain values greater than 20.33 dBi. The LHCP pencil beams are at least 24° off‐broadside, so the proposed hologram avoids the feed blockage. These achievements make the hologram one of the best candidates for satellite communications, radar applications, short‐range communication, and point‐to‐point communication.
