“…Compared with dipole antennas, a shorted wire biconical antenna (SWBA), also denoted as a wideband high efficiency electromagnetic structure (WHEMS), is able to achieve a higher broadside gain of 6 dBi at the 3/2λ resonant mode due to the bending and the short circuit processes [17]. However, in the lower side of the band, the antenna works at the λ resonant mode, where the dimension is large.…”

A broadband compact antenna is proposed in this paper with an enhanced broadside gain performances in the +/-z directions. A design method of complementary gains is presented to overcome the gain reduction caused by the cancellation of reverse currents in the middle of the band of interest, where a design equation of the excited element of the antenna is given. This objective is achieved by accurately analyzing the resonant modes of the two parallel connected antennas of the excited element in order to achieve an overall wideband radiator. An orthogonal radiating choke (ORC) is proposed to remove the gain depression due to the leakage of electromagnetic waves toward the upper portion of the band of interest through simultaneously enhancing the broadside gain and choking the end-fire travelling wave. Each one patch of the ORC acting as both a TM10 mode microstrip antenna and a choke of end-fire travelling wave. With the help of the ORC, the gain in +/-z directions is enhanced by 13.1 dB at 6 GHz compared to that without the ORC. The proposed antenna presents a realized broadside gain of 2.1-7.8 dBi in the +/-z directions within a bandwidth of 158% (700 MHz -6 GHz). Both the simulated and measured results demonstrate that the proposed antenna exhibits desirable bandwidth and gain characteristics and is a promising candidate for broadband integrated wireless systems.INDEX TERMS broadband, broadside, gain, bandwidth, leakage

“…8,9 Although the Yagi array yields higher gain, its interelement spacing of 1.83λ results in larger dimensions, leading to increased wind load. 10 On the other hand, wideband high-efficiency electromagnetic structure (WHEMS) antennas possess smaller end-fire size and wider bandwidth, [11][12][13][14][15][16][17] with relatively smaller interelement spacing, yet they do not exhibit substantial gain improvement. 18 Addressing the coupling issue is pivotal for enhancing the gain of linear antenna array.…”

A compact series‐fed high‐quality linear array antenna for 5G maritime communication is proposed. Building upon the wideband high‐efficiency electromagnetic radiation structure (WHEMS), a linear integrated series‐fed method is proposed, enhancing applicability in maritime environments. A self‐decoupling structure without the parasitic elements is introduced, resulting in a 7 dB increase in isolation while achieving array spacing of less than half the wavelength. The antenna has an impedance bandwidth of 19.9% (676–825 MHz) to cover the maritime 700 MHz application band, a high gain of 13–14.2 dBi, and a smaller volume compared to classical Yagi arrays with the same gain level. Furthermore, it exhibits characteristics such as low wind load, cost‐effectiveness, and high voltage resistance. The proposed antenna will play a vital role in the construction of the current 5G maritime communication network.
