Abstract: The invention relates to an antenna system for electromagnetic waves in a microwave range. At least one directional antenna such as a Vivaldi antenna and/or an omnidirectional antenna such as a dipole antenna, with at least one central unit including at least one active member which is connectible with at least one reception/transmission system is disclosed. To make the system more flexible, the plugged-in antenna is capacitively coupled to at least one motherboard of the central unit and a booster module, an attenuation module, a calibration module, a combiner module, a filter module, or a passive module is optionally pluggable in the central unit to provide a pluggable module. The functionality of the central unit is determined based on the plugged-in module.

Abstract: The invention relates to an improved antenna arrangement which is characterized by the following features: a patch electrode (7) having a patch electrode surface (71) is provided above the dielectric (5) or on the upper face (5a) of the dielectric (5), said patch electrode (7) is fed via a feed line (11) that passes through the dielectric (5) and in doing so is led to a feed point (11a), which is galvanically or capacitively connected to the patch electrode (7). An electrically conductive top patch (23) having a top patch surface (23?) is provided at a distance (D) above the patch electrode (7), said patch electrode (7) and the top patch (23) are arranged perpendicularly to a central axis (Z) passing through the antenna arrangement, said antenna arrangement being formed as a left or right circular polarized antenna arrangement.

Abstract: An improved patch antenna arrangement includes a patch electrode and a frame patch electrode surrounding the patch electrode provided on a dielectric. A top patch is also provided. The top patch is arranged opposite the dielectric at a distance from the patch electrode surface and at a distance from the ring or frame patch electrode surface. The top patch has an extent in the longitudinal and transverse direction, such that the top patch covers both the patch electrode surface and the frame patch electrode surface at least in some sections.

Abstract: A directional coupler including at least two coupled lines and at least three ports is disclosed. A first coupled line of the at least two coupled lines includes at least two ports such as an input port and an output port. A second coupled line of the at least two coupled lines includes a forward path and a backward path that are joined together at a third port to form a loop. To achieve a constant coupling attenuation over a broad frequency band and to minimize dimensions, the second coupled line includes a higher line impedance than the first coupled line, at least two times higher, and a coupling resistor is connected in series either in the forward path or in the backward path. In a multichannel power splitter, directional couplers are arranged in series with one another.

Abstract: A patch radiator has a radiator surface designed as an annular and/or frame-shaped radiator surface, extending around a recess area. The radiator surface is extended so as to transition into the lateral surfaces or lateral walls. On the lateral surfaces or lateral walls, a lateral surface radiator structure electrically connected to the radiator surface is formed. In the peripheral direction of the lateral surfaces or lateral walls, there are lateral radiator surface sections, between which electrically non-conductive recess areas are provided.

Abstract: An antenna capable of receiving both left-hand circularly polarized (LHCP) signals and right-hand circularly polarized (RHCP) signals, and outputting both signals on a single feed. The antenna includes two coplanar concentric patches. The inner patch is substantially square. The outer patch surrounds the inner patch to define a gap therebetween. A resonant parallel inductive/LC circuit interconnects the two patches. The circuit includes a plurality of printed traces within the gap and interconnecting the concentric patches. The gap and each trace function as an LC circuit.
