This paper presents the design, optimization, fabrication, and characterization of an electronically steerable transmitarray with 2 bits of phase quantization per unit cell. The proposed transmitarray operates in linear polarization at Ka-band and is composed of 14×14 reconfigurable unit-cells. Four p-in diodes are integrated on each unit-cell to control the radiated field phase distribution across the transmitarray aperture. The prototype demonstrates experimentally pencil beam scanning over a 120×120-degree window, a maximum gain at broadside of 19.8 dBi, and a 3-dB fractional bandwidth of 16.2%.

“…The challenge is to combine these characteristics with high gain, beam-steering capability and multi-band operation. Mechanical beam steering solutions [1] are cost-effective but tend to be bulkier than their phased array counterparts [11], [12]. However, the feeding network of millimeter wave (mm-wave) phased arrays, both analog and digital, is the main limitation in terms of RF performance and cost.…”

“…Low cost and compact beam steering antenna solutions compatible with high gain are required for mass production. Mechanical steering antennas [1] tend to be a more affordable option than the electronic steering counterpart [2], at the cost of having bulkier solutions. There is an intensive research on compact mechanical steering solutions [3], [4].…”

A new design of planar lenses for mechanical beam steering at Ka-band is presented, which enables achieving simultaneously wide scanning coverage (40 degrees) with high directivity (40 dBi) and low beam distortion (side lobe level below -15 dB and scan loss better than -2.4 dB). The steering mechanism based on in-plane lens translation/rotation has been demonstrated in a previous 30 dBi antenna prototype at 30 GHz. We showed that aberrations, caused by the in-plane lens translation, become more significant with the increase of the lens size. Hence, the presented 30 dBi lens solution cannot be simply scaled to achieve the aimed 40 dBi directivity (a common specification for satellite communications at Ka-Band). Using a PO/GO approach, implemented in CST Microwave Studio ®, we prove that the proposed bifocal design outperforms conventional unifocal phase correction.
