“…As preliminary step, the ICPs of the RWFN and the PCLs of the RPAN are separately designed using a basic cell model that only takes into account one single element as designs presented in [7,12]. Following, both parts individually designed are put together in a full integration antenna evaluating its behaviour.…”

“…However, these slotted waveguides lack in versatility because of the strong dependency between the radiating element and the feeding network. As an alternative, a design with patches instead of slots as single radiator was proposed by authors in [7]. In this case, a clear independency between both the feeding and radiating networks in the design process is then achieved.…”

“…Otherwise for linear polarisation (LP), the new coupling method provides the capacity of antenna reconfigurability by the insertion of structures ( [12]) and devices ( [13][14][15]) externally placed to the waveguide network to achieve a radiation pattern control. Finally in both [7,12], the elements were individually designed with a basic cell model, without taking into account the degradation caused by the coupling effects between adjacent elements. These structures were fed by parallel plate waveguides.…”

A novel method for considering radiating structures independently to their feeding networks is presented. The integration of both parts separately designed suffers a critical misalignment with the theoretical behaviour caused by the mutual coupling effects between adjacent elements. This method analyses radiated near E‐field monitors to adjust the whole antenna after joining both independently designed parts. A linearly polarised patch array fed by a rectangular waveguide with internal coupling patches for X band (11–12 GHz) has been designed to validate the method performance. A double stacked microstrip patch structure with an integrated phase compensation microstrip line has been used as radiating element. The coupling patches inside the waveguide are connected to the external radiating patches by means of metallic probes. The presented method requires changes in the feeding structure as in the radiating elements. Several prototypes have been manufactured and measured: the feeding waveguide structure connectorised, the radiating patches connectorised, the union of both with SMA transitions and the final integration into the complete antenna. 18.5 dBi gain and 85% efficiency peak values, as well as 6% usable bandwidth have been experimentally achieved.

In this paper, a 16-element circularly polarized (CP) Substrate Integrated Waveguide (SIW) linear array antenna with -26 dB Taylor distribution and 2% residue power at 17 GHz is designed. The single element consists of four crossed inclined radiating slots. In this configuration, reflection goals on the linear array are not fully achieved. For this reason a tuning element is included on some of the individual radiating elements, which consists of a pair of metallic vias that greatly enhances the reflection of longest slots. Therefore, the antenna reflection is also improved. A global antenna prototype is manufacture to check the new slot element performance in an array configuration. The specified operation band is 16.3 to 17.7 GHz.

Abstract-A Substrate Integrated Waveguide (SIW) planar array is presented using a right handed circularly polarized (RHCP) element with four crossed tilted radiating slots. In addition, a pair of metallic tuning vias is included to really improve the reflection of longest slots. A corporate feeding network over SIW has been designed for distributing the input signal to 128 radiating elements, divided into 8 progressive wave linear arrays of 16 elements each. The designed planar array has been manufactured and measured to verify the antenna performance. 25.5 dB gain, 2.33 dB axial ratio, as well as 85% radiation efficiency values have been experimentally achieved at 17 GHz. A 3% usable bandwidth (16.75-17.25 GHz) is obtained due to the typical frequency main beam tilt dispersion in the elevation plane of the progressive wave arrays.
