Triangular Slot-Loaded Wideband Planar Rectangular Antenna Array for Millimeter-Wave 5G Applications

A Wideband Rectangular-slot Microstrip Array Antenna for Wireless Applications

This paper presents the design of a 2 x 2 microstrip array antenna suitable for wireless applications. The proposed antenna comprises of 4 rectangular patches where diagonal patches have the same length and width. A larger bandwidth and the desired resonant frequency are achieved because of a reduction in the quality factor (Q) of the patch resonator, which is due to less energy being stored be...

Printed Wideband Antenna for Millimeter Wave Applications

Rectangular Slot Antenna with Patch Stub for Ultra Wideband Applications and Phased Array Systems

This paper presents a coplanar waveguide fed rectangular slot antenna tuned by a patch stub. The presented antenna has 98% impedance bandwidth, and 6 dB average gain. The antenna can be used in phased array applications with more than 61% usable bandwidth.

LTCC Partially-Filled Post-Wall Rectangular-Waveguide Slot Array Antenna in the Millimeter-Wave Band

In the millimeter-wave band, the series-fed array antenna is facing a problem of large transmission loss and narrow bandwidth by using a high-permittivity and large-loss-tangent material. In this paper, an air region is inserted in the half of the height in the LTCC waveguide of εr =6.6 and tanδ =0.013 to reduce the transmission loss. The reduction of the equivalent dielectric constant by the a...

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
