“…It is desirable to compromise between side lobes and beam width. Hence, the dimensions of the slots are optimized by varying the slot length following the results obtained by [4], [5] and so we choose to have non-uniform slots one of a length L s1 = 6mm and the other of a length L s2 = 4.55mm, L s1 and L s2 are distant one from the other with a distance p and repeated periodically on a distance of 220mm, the width of the slots is w s = 0.45mm.…”

“…The low profile and easy manufacturing make them ideally suited for modern communication systems since they give high-quality performance at low cost [8]. This type of antennas is on study these last years using SIW technique, and was analyzed by [5] and then the scanning angle and gain is optimized by [4], [7], [9], good results were obtained. The criticism that has been raised about these new interconnects and components is that they possess a relatively large footprint.…”

A compact Substrate Integrated Waveguide (SIW) Leaky-Wave Antenna (LWA) is proposed. Internal vias are inserted in the SIW in order to have narrow walls, and so reducing the size of the SIW-LWA, the new structure is called Slow Wave -Substrate Integrated Waveguide -Leaky Wave Antenna (SW-SIW-LWA), since inserting the vias induce the SW effect. After designing the antenna and simulating with HFSS a reduction of 30% of the transverse side of the antenna is attained while maintaining an acceptable gain. Other parameters like the radiation efficiency, Gain, directivity, and radiation pattern are analyzed. Finally a Comparison of our miniaturization technique with Half-Mode Substrate Integrated Waveguide (HMSIW) technique realized in recent articles is done, shows that SW-SIW-LWA technique could be a good candidate for SIW miniaturization.

“…Different LWAs based on SIW structure with different and interest properties have been proposed and used [4]- [11]. Two types of uniform LWAs with low and controllable side lobe level were designed using meandering long slots on the broadside of a straight SIW section, and a straight long slot on the broadside of a meandering SIW section [4].…”

In this paper, the design and implementation of a three-band substrate integrated waveguide (SIW) leaky-wave antenna (LWA) based on the composite right/left handed (CRLH) structure is presented. CRLH unit cell of the proposed antenna is composed of two adjacent interdigital slots with two vias between them. Two CRLH bands along with a new right handed (RH) band between them are achieved through this structure. The first CRLH band (7.1-10.75 GHz) is balanced and the second one (15.1-21.75 GHz) is unbalanced with 0.25 GHz stop band. Beam scan angle in the first CRLH band is from -78º to +78º, in the second one from -40º to +20º and in the new RH band (12.6-13.4G Hz) from +22º to +54º. Antenna radiation efficiency in the first CRLH band is about 90%. Simulated and measured results are compared and there is a good agreement between them.Index Terms-leaky-wave antenna, composite right/left-handed transmission line (CRLH TL), substrate integrated waveguide (SIW), three-band.

“…Also, a LWA based on SIW structure with H-shaped slot with scanning capability from broadside to end-fire was proposed in [4]. In [5][6][7] non-uniform transverse slot SIW leaky wave antenna is presented. In [6] a novel bow-tie slotted SIW leaky wave antenna is designed, which has a more uniform spectral response, resulting to improvement in electric field distribution on the slot.…”

In this paper, a new Leaky Wave Antenna (LWA) based on modified substrate integrated waveguide (MSIW) is proposed and investigated. It is shown that MSIW can support the Quasi-TEM mode. Leakage from the antenna is obtained by inter-digital capacitor (IDC) embedded on the top of the SIW. This antenna is simulated by HFSS and the results including radiation patterns, reflection coefficient and antenna gain is reported. The proposed antenna provides a good beam scanning in the both backward and forward radiation Keywords Leaky wave antenna, Modified substrate integrated waveguide, TEM mode, Interdigital capacitor.
