“…In 2019, Hong et al staked six pieces of substrates to obtain more than 7 dB gain than that of the antenna without a radome; however, the profile of the radome is higher than 6 λ 0 . 7 Liao designed a low radar cross-section radome based on frequency selective surface (FSS) to reduce the backscattering 8 ; however, the gain of the antenna reduces when the distance between the antenna and radome is less than 1/4 λ 0 . In 2022, Xing et al co-designed an array antenna with an artificial magnetic conductor-FSS-based radome to achieve low insertion loss and wideband transmission 9 ; however, this radome reduced the gain by 0.42 dB.…”

Traditional radome adversely influences the antenna performance besides protecting the antenna from the outside environment. In this work, one co‐design of a millimeter‐wave antenna and radome using parasitic patches is presented, featuring a low profile and high gain. First, the basic influence of radome on patch antenna is investigated on a transparent and low‐loss material cyclic olefin copolymer. Then, the electromagnetic interaction between the patches and the antenna is investigated in detail to reduce the adverse effect of field reflection and phase delay. One prototype of the co‐designed radome and antenna was fabricated for demonstration. The measured results show that the entire profile of the co‐designed radome and antenna is significantly reduced from traditional 0.5–0.2 λg and the gain is enhanced by 2.4 dB.

“…In 8 , the coverage of the desired direction with beam steering capability ranges from -90° to +90° in theta plane is presented where the scanning capability is obtained by three identical subarrays of patch antennas which are fed by switching to particular subarrays. In 9 , the radiation pattern at mm-wave is distorted by the scattering of the signals. Meanwhile, the damage of the patch antenna is controlled by placing conventional radome on the patch.…”

A planar inverted-F antenna with symmetrical split beams and loaded with radio frequency absorbers (here Eccosorb MCS) for 5G communication is proposed. The multi-beam antennas reduce the requirement of number of antennas and provide wide coverage. But they require a complex system such as a phased array or MIMO antennas. On the other hand, multi-beam antennas do not have such requirements. In this work, we propose a PIFA antenna which achieves multi-beam behaviour by six slabs of absorbers placed periodically between the PIFA patch and substrate to split the beams into two directions at +26°. The proposed antenna obtains a frequency band of 24.2- 25.7 GHz and achieves a high gain of approximately 10 dB at +26°. The performance of the proposed antenna is suitable for G communication. All simulations of the antenna are carried out using Ansys HFSS. The design was validated by simulations and later confirmed with measurements.

A low cost microstrip antenna is designed for mm–wave applications on FR4 substrate. It consist of patch, etched with an open polygon slot (OPS) at lower central edge of it and partial ground plane. This etching of OPS is used to improve depth of reflection co-efficient below -20 dB which is equivalent to mismatch loss (ML dB ) ≤ 0.04 dB. This proposed mm–wave antenna also provides 3 dBi– & 5 dBi–gain-bandwidth of 6 GHz (34.72—40.72GHz) & 3.91 GHz (34.72—38.63GHz) respectively with a peak gain of 12.4 dBi at 35.1 GHz and acceptable radiation efficiency of 58.05 %. Simple design, low manufacturing cost and ease of fabrication makes proposed antenna suitable for high end practical mm–wave applications.
