Embodiment Construction

[0017] According to one embodiment, including Figure 1A to Figure 1E The figure of FIG. 1 shows the antenna 11 . For example, antenna 11 includes a set of spatially offset and differently oriented radiators (26, 28, 126, 128), such as notched semi-elliptical radiators. Each of the radiators has a generally planar first surface 27 (eg, as Figure 1C shown). The ground plane 14 has a generally planar second surface 29 that is spaced by approximately the same spacing 51 (eg Figure 1C shown) is substantially parallel to the substantially planar first surface 27 of the radiator (26, 28, 126, 128). The ground plane 14 has a central axis 21 . The feed member 32 is adapted to transmit an electromagnetic signal to or from each radiator (26, 28, 126, 128) or to communicate with each radiator (26, 28, 126, 128). 28, 126, 128) to transmit signals back and forth. Each of the feed members 32 is spaced radially outward from the central axis 21 of the ground plane 14 . Each feed memb...

Abstract

The antenna (11) includes notched semi-elliptical radiators (26, 28, 126, 128). Each of the radiators (26, 28, 126, 128) has a generally planar first surface. The ground plane (14) has a substantially planar second surface (29) substantially parallel to the substantially planar first surfaces of the radiators (26, 28, 126, 128) by substantially the same spacing. The ground plane (14) has a central axis. The feed member (32) is adapted to transmit an electromagnetic signal to or receive an electromagnetic signal from each radiator. Each of the feed members (32) is spaced radially outwardly from the central axis of the ground plane (14). A ground member (34) is connected to each radiator and is spaced radially outwardly from the feed spacer (32).

Description

technical field [0001] This disclosure relates to antennas for satellite wire receivers. Background technique [0002] Satellite navigation receivers refer to receivers that determine position, such as Global Positioning System (GPS) receivers, Global Navigation Satellite System (GLONASS) receivers or Galileo system receivers. A satellite navigation receiver requires an antenna to receive one or more satellite signals sent by one or more satellite transmitters of a satellite orbiting the earth. Certain prior art antennas do not adequately receive satellite signals at low inclination angles. Receiving satellite signals at low inclination angles is of considerable importance when satellite receivers operate at high latitudes (eg, at the North Pole). Therefore, there is a need for an antenna capable of properly receiving and acquiring satellite signals at an inclination of a target range. Contents of the invention [0003] According to one embodiment, the antenna comprises...
