Embodiment Construction

[0070] figure 1 A first embodiment of a bow-tie antenna assembly 10 according to the invention is shown, comprising a bow-tie structure 11 comprising two antenna lobes 1,1 made of conductive material forming two arm sections, which Arranged so that the end tip portions 6, 6 of the arm sections point substantially towards each other at one location, for example, on a metal ground plane or on the front side of a PCB (Printed Circuit Board) 9 (on figure 1 Middle, upper side) at the center to form the antenna port. The end tip portions 6,6 are here provided with holes or openings 7,7 for flexible mounting of conductive elements (e.g. wires or pins 12,12) located on the metal ground plane or on the rear side (lower side) of the PCB 9. soldered, they are connected to coaxial or microstrip lines or circuits (not shown).

[0071]The bow-tie antenna assembly 10 is constructed of two opposing halves that are fed individually from two centrally located feed points. The two feed poin...

Abstract

The present invention relates to a self-grounded bowtie antenna arrangement (10) comprising an antenna structure (11) comprising a number of antenna petals (1, 1) comprising arm sections tapering towards a respective end tip portion (6,6) and being made of conducting material, the end tip portions (6,6) being arranged to approach a base portion (9) on a first side thereof and to be connected to feeding ports, a specific port being provided for each antenna petal(1,1). The base portion (9) comprises a conducting ground plane or a Printed Circuit Board (PCB), and each antenna petal (1,1)is madein one piece from a metal sheet or similar, and it is adapted to be fabricated as separate units (9), and to be mountable onto a front or back side of the base portion or ground plane(9) by means of surface mounting. The ground plane may be a Printed Circuit Board (PCB), meaning that the bowties can be mounted by automatic placement and soldering machines. Placement machines are more commonly known as pick-and-place machines.

Description

technical field [0001] The invention relates to a self-grounding antenna assembly having the features of the first part of claim 1 . [0002] The invention also relates to an antenna lobe for a self-grounded antenna assembly having the features of the first part of claim 26 . [0003] The invention also relates to a method for producing a self-grounded antenna assembly having the features of the first part of claim 29 . Background technique [0004] There is an increasing demand for wideband antennas for use in wireless communications in order to allow communications in several frequency bands, using high or very high data rates, and for use in different systems. An ultra-wideband (UWB) signal is generally defined as a signal with a large relative bandwidth (bandwidth divided by the carrier frequency) or a large absolute bandwidth. The expression UWB is used in particular for the frequency band 3.2-10.6 GHz, but also for other and wider frequency bands. [0005] The use o...
