Abstract: A single port orthogonally terminal polarized antenna is disclosed herein. The antenna may be used in apparatuses including but not limited to handsets, Internet of Things (IoT) terminals, and vehicles. The antenna significantly reduces the need for spatial diversity multiple-in and multiple-out (MIMO) in terminals.

Abstract: A compact dual narrow band microstrip antenna particularly suited for remote wireless metering includes a dielectric, a directly fed radiating element, a parasitic radiating element gap coupled to the directly fed radiating element and a truncated ground plane. Each radiating element is partially shorted to the ground plane and each radiating element has a reactance window to lengthen the current path. The reactance window and partial shorting reduce the size of the each radiating element. The antenna is compact with good isotropic characteristics and sensitivity to two perpendicular polarizations.

Abstract: A compact planar inverted F antenna suited for remote wireless metering includes a circuit element, a ground plane and a feed probe. The circuit element has a planar portion with a reactance window, and a narrowed tab that extends transverse to the planar portion and is connected to the ground plane. The reactance window and narrowed tab reduce the size of the circuit element. The feed probe is connected between the circuit element and the ground plane. The ground plane has conductive portions that are wrapped around a substrate to reduce the physical size of the ground plane. The length of the tab and thereby the distance between the planar portion and the ground plane is selected so that the feed probe is a radiating element. The antenna is compact with good isotropic characteristics and sensitivity to two perpendicular polarizations.

Abstract: A stacked, shorted double C-patch antenna (100) has gap-coupled parasitic elements (102a, 106a, 102b, 106b) and one directly fed antenna element (104a). A second fed element (104b) is conductively fed from the directly fed element. The antenna has a truncated ground plane (108) and a bandwidth that is equal to or greater than approximately 70 MHz at a frequency of approximately 850 MHz. The directly fed antenna element is conductively coupled to a transmitter and to a receiver of a communications device, such as a cellular telephone.

Abstract: A module (1') adapted for insertion into a data processor (2). The module includes an interface (40) for electrically coupling the module to the data processor, a modem (42) that is bidirectionally coupled to the interface, an RF energy transmitter (44) having an input coupled to an output of the modem, an RF energy receiver (46) having an output coupled to an input of the modem, and a partially shorted, dual C-patch antenna (20) that is electrically coupled to an output of the RF energy transmitter and to an input of the RF energy receiver. The partially shorted, dual C-patch antenna is comprised of a truncated ground plane (22), a layer of dielectric material (28) having a first surface overlying the ground plane and an opposing second surface, and an electrically conductive layer (30) overlying the second opposing surface of the dielectric layer.

Abstract: A wide bandwidth, shorted, dual C-patch antenna includes a truncated ground plane, a layer of dielectric material having a first surface overlying the ground plane and an opposing second surface, and an electrically conductive layer overlying the second opposing surface of the dielectric layer. The electrically conductive layer is differentiated into a plurality of antenna elements including a driven antenna element and at least one non-driven, parasitic antenna element. Each of the antenna elements is in the shape of a parallelogram and has one of a rectangular and a non-rectangular (e.g., parabolic, triangular, pentagonal) aperture having a length that extends along a first edge of the electrically conductive layer and a width that extends towards an oppositely disposed second edge. The length has a value that is equal to approximately 20% to approximately 35% of a length of the first edge.
