A K-Band Aperture-Coupled Microstrip Leaky-Wave Antenna
Microstrip leaky-wave antenna fed by an aperture-coupled microstrip operating at K-band is presented. Using the aperture-coupled microstrip as a feeding structure can fully exploit the wideband characteristic of the microstrip leakywave antenna. The dimensions of the antenna are obtained from the calculation of the propagation characteristics. Measurement shows a bandwidth of 22% for VSWR < 2 :...
متن کاملAn Aperture-Coupled Linear Microstrip Leaky-Wave Antenna Array with Two-Dimensional Dual-Beam Scanning Capability
This paper describes an -band 4 1 aperture-coupled series-fed electronically steerable microstrip leaky-wave antenna (LWA) array design, which has dual-beam radiation pattern and two-dimensional (2-D) beam-scanning capability. The LWA array is operated in the first higher order mode and excited by center-fed aperture coupled for dual-beam operation. The varactor-tuned phase shifters are placed ...
متن کاملA Novel Short Length Half-width Microstrip Leaky Wave Antenna with Suppressed Back Lobes
A novel short half-width microstrip leaky wave antenna (MLWA) with suppressed back lobes is introduced. The design contains an oblique shape termination and a linked square metal with a grounded via hole. The oblique shape termination changes the direction of the reflected wave, and a linked square metal with a grounded via hole guides the remainder power of the reflected wave to the ground pla...
متن کاملBroadband Operation of Microstrip-Line-Feeding Waveguide Aperture Antenna in the Millimeter-Wave Band
Microstrip-line-feeding waveguide aperture antenna is developed in the 70-90 GHz band. A double-layer LTCC substrate is attached to the waveguide aperture opened on the wall of the metal package. The bandwidth over 20 GHz is observed in the simulation and the experiment.
متن کاملLeaky Wave Antenna Using Composite Right/Left- Handed Transmission Line with Rectangular Feeding Structure
A leaky wave antenna (LWA) using composite right/left-handed (CRLH) transmission line (TL) composed of ladder network has been investigated [1]. The effect of transmission line length and height on the gain and bandwidth is clarified in [1]. In order to increase the gain of the LWA, mushroom-shaped unit cell has been investigated in [2]. Chip capacitance is used for series capacitance. The band...
