“…In order to determine the direction of arrival, six sides and the top of the truncated hexagonal pyramid were dispersed with seven coaxially fed microstrip patch antennas [31]. To create the directional array antennas, a few various feeding approaches, including closely linked multifeed, SIW seriesparallel differential feeding network, and centrally fed by substrate integrated coaxial line, were presented [32][33][34][35][36][37][38][39][40].…”

In this article, a broadband semicircular antenna array geometry was examined, along with its design and configuration in the submillimeter wave range (9.35-42.89 GHz). The work has been divided into two prime phases; in the first phase of work, an innovative angular-phased 1 : 4 broadband power divider has been presented in which its isolation, insertion, and return losses are investigated. In the next phase, the proposed power divider was used to configure a 4-element antenna array, and its theoretical analysis was carried out. The angular path difference in the array was used to introduce phase difference in between the antenna elements to minimize the mutual coupling and to optimize the narrow beamwidth. Using geometry and fundamental array theory, the array factor of a novel broadband array configuration has been derived and analytically investigated.

“…Its impedance bandwidth is almost the same as the AR bandwidth. In 2022, Wu et al 7 proposed a full corporate CP planar antenna array based on septum antenna elements and metal ridge gap waveguide, which realized 32.6% AR bandwidth with a 31.4% 10‐dB impedance bandwidth. In these designs, the impedance bandwidth of the antennas is not wide enough.…”

Grooving or subtracting a projection of the antenna on the ground is one of the effective methods to both improve the axial-ratio (AR) bandwidth and impedance bandwidth of a circularly polarized (CP) antenna. A bidirectional radiation, meanwhile, can be produced. Unfortunately, these methods will result in a decrease in the gain of the antenna due to a reduction of its ground size. To solve this issue, a conductive plane or a cavity is usually introduced at the antenna's bottom, but it will lead to a high profile and destroy the bidirectional radiation of the design. In this article, a CP array antenna based on a sequential-phase (SP) feeding network is taken as an example. Only the projection of the feeding network is preserved, while other conductors on the ground are subtracted. The simulated peak gain of this design is only 5.04 dBic. In order to obtain an ultra-wideband, a wide AR bandwidth, a moderate gain and a low profile of the antenna, a method of etching a circle of ground around the edge of the substrate is presented to expand the ground into a large irregular area. The measured results show that the proposed design can exhibit a 90.9% 10-dB impedance bandwidth, a 42.4% (5.2-8 GHz) 3-dB AR bandwidth, a 7.17 dBic peak gain, and a very low profile of 0.006λ L . This method is very simple to implement and does not need to modify the original antenna structure.It may be applied to conveniently improve the performance of the bidirectional radiation CP antenna.
