Abstract A new type of dielectric‐loaded substrate integrated waveguide H‐plane horn antenna with an embedded air cavity is proposed aiming to improve E‐plane performance on a thin substrate. Comparing with recent works, this design attracts superior radiation performance only requiring drilling process to embed a rectangular air cavity in the exte...

... This shows a tendency of the antenna to function with maximum power in the forward direction and cause the shape of the antenna is horn shaped it propels the signals in exorbitant force compared to linear antenna. This seems to be a bit confusing but further analysis will solve the problem [6] [8]. ...
Horn antenna is well documented in our research in this paper. We are trying our latent method of radiation by antennas which we suppose to reduce to a significant extent. Why we chose horn antenna is it resonates the sound to explosion as done by horn shaped matter. Horn by its shape makes the sent signals to maximum capability by its shape which is required by the receiver due to the distance separation from sender and receiver. Our research will contain various implementations leading to improvement of previous designs. We will use the traditional methods of Bergen to make the antenna behave smartly in its functioning.

... In terms of the gain improvement through radiation characteristics for the SIW H-plane horn antenna, various techniques have been developed aiming for a high directivity [10][11][12][13][14][15][16]. A simple approach of extending the dielectric loading to narrow the beam is proposed in [10], and further developed in [11] by reshaping the aperture through the printing metal. ...
Substrate integrated waveguide (SIW) technology that combines 3D and 2D structures has been successfully utilized due to its notable advantages, including in its application to H-plane horn antennas. As this type of antenna is commonly constructed on thin substrates, the E-plane radiation pattern is always wide, thereby limiting the achievable gain performance. In this work, we propose an approach that incorporates 3D printed horns on a prefabricated SIW H-plane horn antenna to successfully narrow the E-plane radiation pattern, thereby improving the gain performance. The proposed E-plane horn is designed at the aperture of the original H-plane horn, providing a smooth and continuous wave transition from the thin substrate to the end-fire direction. This approach improves the directional radiation performance significantly and reduces fabrication time and associated difficulties as the parasitic structures are simply attached to the SIW horn, without the requirement of redesigning or refabricating the original antenna. From 20 to 25 GHz, an optimized prototype shows excellent performance. At 22.7 GHz, it exhibits 35° and 33° for the E- and H-plane half-power beamwidths (HPBWs), with corresponding side-lobe levels (SLLs) of −23 dB and −15 dB. The present research reveals that the proposed design presents high feasibility and a reduced demand for high-precision manufacturing processes at a lower cost, concomitantly providing an effective means to further improve on the radiation characteristics.
