Abstract-A cavity backed conformal broadband compact hexagonal patch antenna is proposed that is fed using a co-axial probe. This horizontally mounted shorted antenna yields vertical polarization. The antenna yields 9.52% bandwidth centered around 1.05 GHz. The simulated results of electrical parameters of this antenna are in good agreement with measured ones. This vertically polarized antenna can be used for IFF airborne applications.

“…Many other studies have partially benefited, intentionally or unintentionally, from the enhanced bandwidth of the small size of the antenna [38]- [39], but without any explanation or optimization process of the size. To the best of our knowledge, the variations of performance due to the antenna size have not been intensively investigated in literature in spite of its strong influence as indicated in [40].…”

We develop a high-gain antenna with wideband operation and compact size by placing a small dielectric superstrate (puck) in front of the feeding antenna. The antenna performance is a combination of the leaky-wave effect, naturally existing in this type of antennas, and the edge diffraction effect occurring at the puck perimeter. Compared to the typical resonant cavity antenna utilizing a large superstrate, the proposed puck antenna has nearly four times enhanced performance (gain-bandwidth combination) while using a square puck of side slightly smaller than two wavelengths (at the design frequency). Further enhancement is achieved by making the puck circular in shape in order to add the diffracted fields in phase. The study is conducted through full-wave simulations and validated through measurements in the Ku band. The effect of puck misalignment is then discussed as a potential practical issue. Last, the ground plane is optimized for maximum antenna performance and relatively acceptable values of aperture efficiency (up to 51%).

“…There are many requirements on the material for insertion, such as low permittivity and matched coefficient of thermal expansion (CTE). The cavity backed antenna has better performance [5][6][7][8] because it makes the effective permittivity of substrate closer to that of vacuum. However, considering the low cost and high reliability, the fabrication process is difficult to handle.…”

This letter demonstrates a technique for a folded slot antenna fabricated on low resistive silicon wafer, using pre-etched cavity and Benzocyclobutene (BCB) support membrane. The most distinctive feature of this method is that a cavity is pre-etched before the antenna fabrication process using low-cost potassium hydroxide (KOH) wet etching. BCB membrane is employed to support the antenna above the cavity for its low permittivity as well as excellent thermal and mechanical stability. The fabrication process discussed in detail and the fabricated antenna was characterized. Experimental results show that the antenna resonates at 15.4 GHz with a very wide impedance bandwidth, up to 14.6%.
