“…In particular, for the military system, recent missile seekers are often required to employ such Ka-band antennas for a low-cost, lightweight, and small antenna size because of a single explosion. The missile seeker antennas are conventionally designed by using 3D structures, such as a Vivaldi type [9,10], a horn type [11,12], a rod type [2,13], and a Yagi-Uda type [14,15], to provide a high directive pattern for precise target tracking. However, these antenna designs have a bulky size and an expensive fabrication cost because their feeding networks commonly need metallic waveguide structures and a sophisticated fabrication process.…”

This research proposes a compact indirect slot-fed wideband patch array antenna for a missile seeker application. The proposed single antenna consists of three dielectric layers for a radiator, an air substrate-integrated waveguide (SIW) cavity, and an indirect feeding network. The rectangular patch is used as a radiator on the first substrate layer, and the air SIW cavity (ASIWC) is employed to obtain high directivity and low mutual coupling characteristics in the second substrate layer. In the third layer, an indirect feeding structure is used to achieve the wideband characteristics in the Ka-band. The single element is extended to a 4 × 1 linear array with fabrication, and the fabricated array characteristics are measured in a full anechoic chamber. The measured operating fractional frequency bandwidth is 9.2%, and the measured array gain is 11.7 dBi at the bore-sight direction (θ0 = 0∘).

“…The electrical size (kr) is a criterion that combines the wave number, k, and the radius of a sphere, r, enclosing the antenna to convey an antenna's size according to its wavelength. It is shown from the Chu limit that as kr gets smaller, so does the radiation efficiency and impedance bandwidth product [18][19][20]. Thus, a balance between kr and broad CBW is desired.…”

A bidirectional, circularly polarized antenna with a miniaturized design and broadband capabilities is proposed for consideration in WLAN 2.4/3.65-GHz, WiMAX 2.3/2.5-GHz, 4G, and 5G frequency bands. The front side of the antenna consists of a hexagonal slot, a hexagonal patch, ten meander tips, and rectangular corner notches to achieve broad impedance and axial ratio bandwidth. The feedline on the backside of the antenna with accompanying shorting pin is offset to further increase the common bandwidth. Also, the four corners of the antenna substrate are removed to decrease the electrical size. The designed antenna is fabricated and measured to validate simulation results. From measured results the antenna has a −10-dB impedance bandwidth of 89.7% (1.60-4.20 GHz) and a 3-dB axial ratio bandwidth of 70.5% (1.80-3.76 GHz). The peak realized gain in the boresight direction is 3.65 dBi, which occurs at 1.88 GHz.
