Embodiment Construction

[0032]The disclosed apparatus and method provide a low profile miniaturized broadband antenna for use in modern wireless applications. In general, multi-layer multi-strip configurations are used to overcome the known conflict between size reduction and bandwidth widening in patch antenna design. In particular, the disclosed devices and methods incorporate a folded main patch having two radiating edges, one or more parasitic patches coupled to the main patch and / or coupled to one or more parasitic strips and Various combinations of one or more shorting bars between the ground planes are used to achieve a significant size reduction in all dimensions and a significant widening of the proportional bandwidth relative to conventional patch antennas.

[0033] 1-6 generally depict an exemplary broadband multiple-strip antenna 100 . More specifically, Figure 1A and Figure 1B Antenna 100 including antenna block 110 and ground plane 106 is depicted. Antenna block 110 includes surrou...

Abstract

A system and method for providing a broadband patch antenna including a main patch having first and second strips positioned around a ground strip (102) extending from a ground plane (106) is disclosed. (101), wherein at least a portion of the first strip of the main patch is disposed above the ground plane and forms a first radiating edge with the ground strip, and at least a portion of the second strip of the main patch is disposed above the ground plane. Below the ground strip and forming a second radiating edge with the ground plane. Parasitic patches (103, 104) are coupled to the primary patch along at least a portion of the non-radiating edge of the primary patch.

Description

technical field [0001] The present invention relates generally to antennas, and in particular, the present invention relates to multi-layer patch antennas. Background technique [0002] The background technology provided herein is for the purpose of generally presenting the context of the disclosure. Aspects of the inventor's work to the extent described in the Background Art and descriptions that may not otherwise serve as Background Art at the time of filing are not expressly and implicitly identified as Background Art contrary to the present invention. [0003] Wireless communication requires the use of antennas to transmit and receive electromagnetic signals. Several antenna types are available for various purposes and the selection of one type or another typically depends on the particular application of the antenna. To select an antenna, various operating characteristics of the antenna can be evaluated and compared to determine the type of antenna that offers the mos...
