Resonant Frequency Of Slot Antenna
Resonance behavior of single ultrathin slot antennas on finite dielectric substrates in terahertz regime
- Another antenna that resembles a cavity backed slot antenna is the patch antenna, or microstrip patch antenna. This is shown in in Figure 28.4. This antenna also radiates eciently by resonant tunneling. The resonant frequency of the patch antenna (top of Figure 28.4) is roughly when Lis half a wavelength.
- Resonance frequency by adjusting the length of slot antenna. The simple structure of single linear slot antenna is shown in Figure 1. Slot antenna L1 W1 Lm1 W Microstrip ground Figure 1: Simple structure of linear slot antenna. The length of linear slot antenna L1 is designed for 2.44GHz which referred with wavelength in the substrate ‚g that.

Resonant Frequency Of Slot Antenna Mounts
Abstract:The objective of this paper is Implementation of a microstrip U-slot antenna based on the resonant frequency with High-Frequency Structure Stimulator. In our method, we design an antenna with a range of 1.157GHz, and we improve the gain by placing an array of the antenna. In an antenna such as a Yagi this is caused by a reduction in the currents in the parasitic elements as the frequency of operation is moved away from resonance. For beam antennas such as the Yagi the radiation pattern bandwidth is defined as the frequency range over which the gain of the main lobe is within 1 dB of its maximum.
We investigate resonance behaviors of optically thin metallic slot antennas on finite substrates in terahertz frequency regime. By carefully analyzing theoretical and experimental results, we observe that slot antennas fabricated in a gold film with a thickness below the skin depth of gold show blueshifted resonance frequencies for the increasing slot width, while the opposite resonance behaviors appear when the slot antennas are perforated in perfectly electric conductor. In addition, we find that for slot antenna sustained by a finite substrate its thickness and the slot width are additional crucial factors determining the resonance frequency of slot antennas.
