Planar L-strip fed broadband microstrip antenna

A Broadband Slope-strip-fed Microstrip Patch Antenna

A novel slope -strip feeding technique for a microstrip antenna is presented in order to achieve a broad bandwidth. The experimental results show that the optimal bandwidth attained is 53.4% for less than -10-dB return loss. ® 2004 Wiley Periodicals, Inc.

Broadband Shorted Plate Proximity Fed Rectangular Microstrip Antenna

Measured Performance of Microstrip-Line-Fed Broadband Waveguide Aperture Antenna

Millimeter-wave technologies are expected to realize broadband high-speed wireless communication systems for home server and HD video transmission. Multi-layer substrate such as LTCC configuration is well-known to integrate many RF-circuits into small area of the substrate [1]. We have already been developed broadband microstrip-to-waveguide transitions composed of a substrate and metal parts [...

Vertical-Strip-Fed Broadband Circularly Polarized Dielectric Resonator Antenna

A vertical-strip-fed dielectric resonator antenna exhibiting broadband circular polarization characteristics is presented. A broad 3 dB axial ratio bandwidth (ARBW) is achieved by combining multiple orthogonal modes due to the use of a special-shaped dielectric resonator. The proposed antenna is fabricated to evaluate its actual performance capabilities. The antenna exhibits a measured 3 dB ARB...

Broadband Stacked Microstrip Patch Antenna for L-Band Operation: FDTD Modeling

This paper presents a novel implementation of an electromagnetically coupled patch antenna using air gap filled substrates to achieve the maximum bandwidth. We also propose an efficient modeling technique using the FDTD method which can substantially reduce the simulation cost for modeling the structure. The simulated results have been compared with measurement to show the broadband behavio...
