“…In the millimeter wave band, the continuous transverse stub (CTS) antennas 9–15 had been the popular choice to meet the requirements of high‐performance array antennas. In Reference 11, a new CTS frequency‐scanned antenna was evaluated by using the waveguide technology for millimeter applications.…”

“…Combining with the SIW technology, a CTS antenna was in Reference 13 studied for beam steering applications. By adopting multiple section stepped‐impedance transformers, 14 the radiation slots can achieve a wide impedance bandwidth of 26 to 40 GHz. It has the advantages of high efficiency (over 75%) and a low cross‐polarization level of less than −46 dB.…”

A compact, high‐gain 32 × 32‐horn array antenna with wideband and low side‐lobes for millimeter‐wave applications in the E‐band (71–86 GHz) is presented. The antenna is composed of four metallic layer structures under the waveguide‐feeding. The top layer contains the horn elements and the bottom layer is a corporate‐fed network. From top to bottom, the 2 × 2 cavity‐backed sub‐arrays and the T‐shaped waveguide junctions are loaded in the middle layers. The RF signal from the planar 1–256 ways divider is fed to the horn elements. Due to the uniform excitation, the antenna acquires the high‐gain pencil beam. To verify this design concept, the antenna has been fabricated, measured, and evaluated. Experimental results show that the antenna array has achieved an improved bandwidth (|S11| < −10 dB) in the range of 71–86 GHz (19.1%). More importantly, the peak gain of the proposed antenna keeps a high value of around 38 dBi with the ETSI (European Telecommunications Standards Institute) class II radiation pattern envelope (RPE).

“…In [ 10 ], an antenna array with 16 patches achieved 19.88 dBi gain, with the maximum beam at the boresight near 28 GHz; however, the array did not utilize methods to reduce SLL, and the value was limited to −13.4 dB. The other dipole, patch and aperture antenna arrays for 5G millimeter-wave applications also showed limited SLL values near −10 dB to −15 dB [ 11 , 12 , 13 , 14 , 15 ].…”

A corporate feeding antenna array with parasitic patches has been investigated previously for millimeter-wave applications due to its high gain and wide bandwidth. However, the parasitic patch integration in the uniformly powered and spaced patch antenna array led to a high sidelobe level (SLL). In this study, we designed a non-uniformly powered and spaced corporate feeding network to feed a 12-element parasitic patch-integrated microstrip antenna array for SLL reduction at 28 GHz in the millimeter-wave band. In the power divider, we arranged two one-to-six unequally feeding power dividers from the opposite side to feed 12 antenna elements with non-uniform excitation, and effectively controlled the spacing between antenna elements. The two opposite input ports from the power divider were fed 180° out-of-phase for good isolation between the adjacent antenna elements. To verify the SLL reduction effect from the non-uniform spacing in the array, we designed two non-uniformly powered patch antenna arrays with uniform and non-uniform spacing. In the measurement, the non-uniformly powered and spaced patch antenna array demonstrated a nearly 16.56 dBi boresight gain and −17.27 dB SLL, which is nearly 2 dB lower than the uniformly spaced counterpart. Finally, we expect that the non-uniformly powered and spaced high gain patch antenna array with a low SLL will be suitable for millimeter-wave communication applications.

“…Arraying many identical planar radiating elements is one straightforward method to increase the gain of the antenna [2], [3]. But, antenna arrays, if not used for beam steering, are unnecessarily complex and requires a feed network which itself increases the loss in the antenna system.…”

Dual-Band High-Gain Planar Corrugated Antennas With Integrated Feeding Structure

In this paper, a dual-band high-gain planar corrugated antenna is presented for applications in space and satellite communications. An analytic method based on the unit-cell analysis of a corrugated structure is presented to estimate the resonant frequency of the corrugated antenna where the maximum broadside gain happens. Therefore, the design of periodic corrugated antenna structures, which is very timeconsuming due to the large size of the structure, is reduced to the design of a unit-cell of the structure which is very fast. A 2D corrugated (bull's-eye) antenna structure is then parametrically studied to find the parameters which affect the resonant frequency of the corrugated structures. A dual-band bull's-eye antenna with an integrated feeder structure at center is designed for the center frequencies of 9.7 GHz and 13.85 GHz. The dual-band operation is enabled using two different corrugations realized on two laminate boards. A prototype is fabricated and measured maximum broadside realized gains of 15. 8 and 17.5 dBi are achieved for the first and second bands, respectively. INDEX TERMS Bull's-eye antennas, corrugated structures, corrugation susceptance, dual-band antennas, high gain.
