This paper presents the design of stacked suspended plate transmitter antenna for digital video and audio broadcasting. Contrary to conventional dipole structures, we have designed the antenna in VHF band (174–254 MHz) with two plates for wideband matching and design flexibility. Radiating primary plate has been excited by novel wideband modified inverted L‐type probe. Parasitic secondary plate, and vertical wall between primary plate, and ground plane have been used for further matching and beamwidth adjustment. A bandwidth of 42% and gain of 8.5 dBi is obtained at center frequency. Together with equivalent lumped element circuit model of designed antenna and experimental results for S11, gain, and radiation pattern are presented. To the best of authors knowledge this is the first stacked suspended plate antenna achieving a record bandwidth of 42% in VHF band.

“…The paper present a hybrid water antenna operating at very high‐frequency (VHF) band, in which a simple seawater monopole is loaded with two distilled water cylinders working as dielectric resonators (DRs). A VHF microstrip patch antenna was developed to achieve a bandwidth of 45 MHz with dual‐linear‐polarization capability. Due to the additional loading technique, the size of these antennas is not small enough for some application with stringent demands of miniaturization.…”

Haksu and Gil‐Young proposed a very low‐profile wideband antenna operating from 30 to 300 MHz, while its weight is as heavy as 9.07 kg due to the employed ferrite.…”

A novel ultra‐small cavity‐backed sector antenna with fractal transmission lines (FTLs) and negative refractive index transmission lines (NRI‐TLs) is proposed in this paper. The proposed antenna comprises three parts. The first one is a U‐shaped cavity‐backed antenna composed of a planar double‐sector patch and a U‐shaped backed‐cavity. The other two parts are FTLs and NRI‐TLs, respectively, both of which are used to achieve bandwidth enhancement and size reduction for the U‐shaped cavity‐backed antenna. Although the U‐shaped cavity‐backed antenna and the proposed antenna have the same size of 36 cm × 40 cm × 25 cm, the proposed antenna can operate in a lower frequency band. Due to the introduction of the negative refractive index transmission lines, the overall size reduction is up to 12.3%. With features such as ultra‐small size, moderate bandwidth and good radiation property, the proposed antenna can meet the demanding requirements to the application of UAV airborne system.

“…In simultaneous transmit-receive applications, dual polarized antennas with two-port connections offer an alternative to the usual bulky combination of circulator and separate transmitreceive antennas. Modern and future airborne radars are looking for the capabilities of high-resolution, real-time, and in situ hazard monitoring that dual polarized antennas are able to provide [6][7][8]. As the airborne applications are concerned, such as the radar, communications, and surveillance systems, the array antenna should feature good isolation, high efficiency, and ease of integration with aerial vehicles.…”

A dual-polarized X-band conformal array antenna is presented for unmanned aerial vehicles with polarimetric radars/sensors. Starting from the planar structure, the array antenna consisted of sixteen 2 Â 2 subarrays is conformal to the cylinders with various curvature radii to fit the payload box of the airborne vehicle. The return losses are almost constant even if the curvature radius changes. Measured radiation patterns are compared with various curvatures at the same frequencies. The array can be easily placed on the aircraft payload or fuselage due to its ultra thin thickness, ultra lightweight, and conformal structure, which has potential airborne applications in polarimetric radar surveillance, remote sensing, and wireless communications.
