“…Typically, there is not much discussion about component selection for beam-steering applications employing varactors and p-i-n diodes. For example, Ka -band designs commonly use the p-i-n diodes MADP-000907 and MA4AGP907 but do not provide a reason for their selection [ 14 , 15 , 16 , 20 ]. Furthermore, varactors have not been utilized in beam steering in the Ka -band to the best of the authors’ knowledge.…”

Intermediate phase shifting is a footprint- and cost-reduction technique for reconfigurable feed networks. These feed networks are utilized in antenna arrays to perform electrical beam steering. In intermediate phase shifting, a phase shifter is shared between two adjacent antennas. Conventionally, antennas only have individual phase shifters. With shared phase shifters, we reduce the number of components and the footprint by 25%. Consequently, this decreases the price and enables designs at millimeter-wave frequencies where space is limited due to frequency-dependent antenna spacing. This intermediate phase shifting is demonstrated by designing a reconfigurable feed network for the Ka-band that generates a continuous phase shift profile for beam steering. Due to the use of varactors and a novel biasing method, it does not require expensive beamformer integrated chips or lumped components for biasing. The feed network is combined with a 4 × 4 antenna array to demonstrate its beam-steering capabilities. The result is a high-density and minimalistic design that fits in a small volume of 25.6 × 25.6 × 0.95 mm3. With this small antenna array, the main beam is steered at ±40∘ broadside, providing full 1D and restricted 2D steering. It is a potential candidate for wireless sensor and mobile networks.

“…Dielectric patch antenna loaded with parallel slots excited via differential feed in Wang et al 9 By loading the slots with PIN diodes, five radiation patterns are achieved with low cross‐polarization. Stacked patch antenna excited with parasitic elements on different substrate 10 showed beam scanning capability from −55⁰ to +55⁰.

This paper presents the design of multiband frequency reconfigurable patch antenna with switchable radiation pattern and polarization states. The antenna design is based on a circular patch radiator with a pair of metallic strips placed on diametrically opposite sides of it. Circular polarization (CP) from the antenna is excited by etching a pair of slots with a coaxial feed. When the diodes are OFF, the antenna resonates at 4.2, 6.6 GHz, (C band) and 8.07 GHz (X band) and the main beam is located at 0⁰ with CP at X band. The resonance at 4.2 and 8.5 GHz are observed when one of the diode is ON. The main beam at X band is being shifted from −30⁰ to 0⁰ and +30⁰ in the elevation plane during the change in operating modes. Peak gain of the antenna is 6 dBi in all the operating modes.

“…For conventional patch-based phased array systems, the beams can only be steered within ±60°, with a scan loss up to 6 dB, due to limited beamwidths of conventional array elements. [1][2][3] To solve this problem, specially designed wide-beam elements 4,5 or patternreconfigurable elements 6,7 have been proposed to extend the scan range. However, the implementation of such elements either requires complicated structures or integrates lumped switching components such as PIN diodes, resulting in increased volume occupation and additional power consuming.…”

Wide‐angle beam steering achieved by an array‐fed phase reconfigurable metasurface

In this letter, we propose and experimentally demonstrate a space‐fed beamforming approach capable of steering beams up to ±70° with a focal ratio (F/D) reduced to 0.27 and a scan loss remained 4 dB. It is implemented based on an mmWave phase reconfigurable metasurface, and an unconventional array‐fed architecture. By doing so, while the total profile of conventional space‐fed phased arrays can be significantly reduced, specifications such as scan range and scan loss can be simultaneously improved. Compared with conventional phased array systems, such specifications are unique, and can be used to realize low‐profile, cost‐effective, space‐fed phased arrays requiring ultrawide coverages at mmWave frequencies.
