Embodiment Construction

[0048] In the following description of various illustrative embodiments, reference is made to the accompanying drawings which form a part hereof, and in which is shown by way of illustration how the various embodiments may be practiced. It is to be understood that other embodiments may be utilized and structural and functional modifications may be made without departing from the scope of the present principles.

[0049] The disclosure herein describes a low profile folded metal antenna suitable for antenna arrays. In one aspect of the present disclosure, the radiating elements of the low height folded metal antenna do not protrude at right angles from the spacers of the balun separating the dipoles. In contrast, low-height folded metal antennas have dipole elements that remain substantially in the plane of the metal sides of the balun, where each metal side is separated by a spacer. As a result, arrays of these antenna designs can advantageously be mounted at antennas closer ...

Abstract

A folded metal dipole antenna includes a balun having two sides, the sides having metal contact end portions for electrical connection to a printed circuit board, two radiating elements, each radiating element in coplanar relationship to a corresponding side of the balun, and an antenna support member having a spacer portion placed between the two sides of the balun. The spacer portion is used toseparate one radiating element of the dipole antenna from another radiating element of the dipole antenna.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 62 / 522,760, filed June 21, 2017, which is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The present principles relate to antennas, in particular to folded metal antennas to be mounted on a non-conductive surface and connected to a printed circuit board. Background technique [0004] Folded metal antennas such as described in PCT application PCT / US17 / 26597 describe an antenna and mounting arrangement which provides means for mounting a folded metal antenna to an antenna support structure which also includes a - Non-metallic spacers for baluns. The radio frequency (RF) is connected to the radio frequency circuit on the PCB via metal contacts connected to the printed circuit board (PCB). The complete antenna arrangement is mounted on the non-metallic antenna support structure, but the portion of the folde...
