The present invention is a dual frequency and circularly polarized microstrip antenna with a ground plane, a mid layer above the ground plane with a parasitically driven resonant mid patch (for transmissions at a second frequency), a top layer with a directly driven patch parasitically driving the mid patch (for transmissions at a first frequency), and parasitic elements.

The present invention antenna preserves the general size and form factor of the prior art loop antennas while providing the benefits of multiple point feeds at less than one wavelength in separation of feed points. The invention antenna obtains omnidirectional radiation and improved efficiency over the prior art by way of dual slotted, open ended cylindrical or rectangular box structures fed with high impedance feed lines.

A vehicle antenna for a cellular telephone has a balanced-unbalanced (BALUN) transformer that is connected to the telephone and is coupled to a horizontally polarized antenna on the interior of the vehicle and to a vertically polarized antenna that is located on the exterior of the vehicle. The vertically polarized component of a received signal is combined with the horizontally polarized component of the same signal in the transformer element and is applied to the cellular telephone. Signals to be transmitted are applied to the the transformer element and are divided into two portions, one of which is applied to the vertically polarized antenna and the other of which is applied to the horizontally polarized antenna. Because signals from a remote cellular transmitter cell arrive with both a vertical and a horizontal component, the antenna of the present invention retrieves the horizontal component which would otherwise be lost and combines it with the vertical component for more reliable signal reception.

An aviation antenna assembly may include a base portion for operably coupling the antenna assembly to an aircraft body, a support platform, and a plurality of antenna elements including a first antenna element, a second antenna element, a third antenna element, and a fourth antenna element. The support platform may be operably coupled to the base portion to support each of the first, second, third and fourth antenna elements uniformly distributed about a central axis. The support platform may support the first antenna element opposite the third antenna element relative to the central axis, and support the second antenna element opposite the fourth antenna element relative to the central axis. A line intersecting a center of the first and third antenna elements may form a 45 angle relative to a line of symmetry passing through the antenna assembly.

An aviation antenna assembly may include a plurality of antenna elements, a directional control switch associated with each of the antenna elements to enable each of the antenna elements to transition between transmitting via a transmission via a transmit chain or receive via a receive chain, beam forming network elements disposed in the transmit chain and the receive chain, and an electronically controlled phased array stirring assembly operably coupled to the directional control switch of each of the antenna elements and to the beam forming network elements to perform electrical stirring with respect to signals in the transmit chain and the receive chain. The antenna elements, the directional control switch, the beam forming network elements, and the electronically controlled phased array stirring assembly of the antenna assembly are all disposed within a single radome attachable to an aircraft body.
