Profiled Horn Antenna with Wideband Capability Targeting Sub-THz Applications

A Capacitive Fed Microstrip Patch Antenna with Air Gap for Wideband Applications (RESEARCH NOTE)

In this paper a microstrip antenna on a suspended substrate with capacitive feed is presented. capacitive feed is created by a slot within the rectangular patch around the feed point. The proposed antenna exhibits a much higher impedance bandwidth of about 47% (S11 < −10 dB). Effects of key design parameters such as the air gap between the substrate and the ground plane, the gap width between r...

A Novel Dual-polarized Double-ridged Horn Antenna for Wideband Applications

Dual-polarized antenna is widely used in communication systems such as ECM and DF systems. In this paper a novel doubleridged horn antenna with dual polarizations is introduced for frequency range of 8–18 GHz. Common double ridged horn antennas have single polarization over the operating frequency. We have used five layers polarizer to provide dual polarizations performance of the doubleridged ...

From Simulations to Measurements: Prototyping an Antenna for Non- Linear Applications at Sub-THz Frequencies

The simulated characterisation and tuning of prototype antennas prior to manufacture is described in this article. The antennas incorporate Schottky diodes so as to frequency triple incident subTHz power. Such a dual frequency, nonlinear, device has been called a multenna. A metrology is outlined for ease of multiple measurements to permit exploring scenarios of multenna element design. Four op...

Printed Monopole Antenna Technology for Wideband Applications

Broadband planar monopole antennas have attracted their candidature for wideband applications like WLAN, WiMAX, RADAR, Satellite etc. Eventhough planar monopole antennas have several advantages in terms of cost, compactness, conformality, simplicity they suffer from a major disadvantage of having very narrow bandwidth. Various planar configurations such as circular, triangular, rectangular, hex...
