“…In Reference , authors have used two 45° inclined interdigital slots on two different leaky‐wave radiators to achieve the polarization flexibility. In References , many spoof plasmon polariton and Goubau line‐based LWAs have been reported but all of them operate in a single band. In References , many multiband LWAs have been reported as in Reference , a mu‐negative (MNG) transmission line‐based LWA is proposed for wide beam scanning.…”

“…In Reference , conventional CRLH transmission line‐based dual‐band and triple‐band LWAs have been reported where the “U”‐shaped slots have been etched from the top conductor of the conventional SIW structure. But unfortunately, all of these antennas generally operate with either LP or CP mode . So, it still remains as a challenge for the antenna designers to design a compact dual‐band dual‐polarized LWA which can scan in both the forward and backward direction with respect to the broadside with good gain and efficiency.…”

In this paper, a novel dual‐band dual‐polarized leaky‐wave antenna (LWA) with polarization diversity is proposed using half mode substrate‐integrated waveguide (HMSIW)‐based technology. HMSIW LWAs are generally single band. In this work, by etching simple spiral type slots on the HMSIW cavity, a novel dual‐band dual‐polarized LWA is designed. The proposed antenna resonates at 5.6 and 8.5 GHz. Moreover, the antenna radiates the linearly polarized wave in the lower band and circularly polarized (CP) wave in the higher operating band. Also, in the higher operating band between 8.7 and 9.3 GHz, the proposed overall antenna exhibits both right‐hand circular polarization as well as the left‐hand circular polarization in the near main beam direction. The −10 dB impedance bandwidth of the proposed antenna at the lower and the higher operating bands are 27% (4.86‐6.4 GHz) and 25% (7.4‐9.6 GHz), respectively. In the higher band, the 3‐dB axial ratio bandwidth of 6.6% (8.7‐9.3 GHz) is achieved. The main beam of the antenna can be steered from 19° to 69° in the forward direction in the lower operating band. In the higher operating band, the antenna can steer the CP beam between −17° and −32°. In both the lower bands, the realized peak gain is observed around 13.3 dBi, whereas in the higher band, the realized peak gain is observed around 14 dBi.

This article presents and validates a leaky‐wave antenna by using the spoof surface plasmon polariton (SSPP) technique. By properly designing the proposed SSPP unit, the SSPP wave can be switched between the confinement and radiation modes. A large radiation efficiency can be achieved by properly designing the modulation depth, which ensures that a compact SSPP leaky‐wave array can be realized by using a small number of SSPP radiation units. To verify the design, a prototype which consists of a SSPP feeding network and a 4 by 4 SSPP radiation units has been fabricated by using a low cost FR‐4 substrate. A good agreement between simulated and measured results has been obtained. The proposed array antenna shows the promising capability of the SSPP technique for leaky‐wave antenna applications.

“…Searching a low-cost means to measure the distance and angle of targets is always a great challenge in the commercial radar sensors researches [1][2][3][11][12][13][14][15][16][17][18]. In recent years, with the attractive advantages such as low profile, compact structure, wide frequency band, frequency beam scanning characteristics and easiness of integration with planar circuits, scientists and researchers have paid much attention to planar leaky-wave antennas (LWAs) [2][3][4][5][6][7][8][9][10].…”

“…Typical frequency-scanning antenna arrays operate based on two basic mechanisms: one is the radiating function, and the other is the frequency-dependent phase shifter function [7,[13][14][15][16][17]. Because the phase adjustment can be realized through the change of frequency, the radiated beams can scan in the space as frequency changes [2].…”

Abstract-Leaky-wave radiations are usually generated by leaking the electromagnetic energy gradually over a structure. By using the coupling effect and leaky-wave properties, this paper designs a novel 1-D frequency scanning antenna array. The antenna is intended for the direct imaging radar sensors. The simulated results show that the scanning angle can stay in the range from −60 • to 30 • . The proposed 1-D antenna array was manufactured, and the measured results are consistent with the simulated ones.
