Experimental and Theoretical Investigations of Folded-Slot Antennas for Quasi-Optical Arrays
نویسنده
چکیده
Folded slots are attractive for active arrays because of their broad bandwidth and simplicity. They have been used recently in a quasi-optical amplifier array. However, little is known about these antennas on thin substrates. The finite-difference time-domain (FDTD) method is applied to the analysis of cpw-fed folded-slot antennas. This paper compares the theoretical results and measured data and provides some design information for folded slots.

Foldedand multiple-slot antennas have been used for quasi-optical arrays. However, there is lack of information of these antennas, especially on finite substrates. In this paper, CPW-fed foldedand multiple-slot antennas are analyzed using FDTD technique with improved absorbing boundary condition (PML method). The effects on the effective dielectric constant and input impedance due to substrate ...

Integrated antennas have been the focus of increasing research activity, particularly for millimeterwave power combining and“quasi-optical” arrays. This paper reviews some of the work in integrated antennas for oscillator and amplifiers arrays carried out at UCSB. This includes unusual phenomena involving coupled-oscillator systems that have led to novel beam scanning concepts for cost-effectiv...

In In this paper, two low profile, single fed cavity backed slot antennas providing a circularly polarized (CP) wave are introduced. One of the antennas presents a right-handed CP (RHCP) wave, while the other one offers a left handed CP (LHCP) wave. The proposed antennas consist of a square shaped Substrtae Integrated Waveguide (SIW) cavity incorporatng two couples of radiating slots to radiate...
