Abstract:
Systems, methods, and circuitries are disclosed for providing a retrodirective array. One example retrodirective array includes a plurality of dual-polarized antenna elements configured to receive a pilot signal having a first polarization and phase conjugation circuitry. The phase conjugation circuitry includes, for each of the plurality of antenna elements, a mixer configured to mix the pilot signal with an LO signal to generate a phase conjugated signal and excitation circuitry configured to generate an excitation signal for the antenna element to transmit the phase conjugated signal with a second polarization that is different from the first polarization.

Abstract:
A microwave antenna apparatus comprises a semiconductor element and an antenna element embedded into a mold layer, which is covered by a redistribution layer. The antenna element is preferably configured as SMD component so that it can be handled by a standard pick and place process. The coupling between semiconductor element and antenna element is provided either by a metal layer or aperture coupling within the redistribution layer. The microwave antenna apparatus may be coupled to a PCB arrangement thus forming an embedded wafer-level ball grid array (eWLB)or embedded micro-wafer-level-packaging (emWLP) package.

L'antenne ULB (Ultra Large Bande) pour les télévisions par satellites et principalement dans la bande X alimentée via une fente dans le pian de masse. L'invention concerne une antenne originale rectangulaire de substrats rectangulaire et de deux patchs rectangulaires. C'est un dispositif d'émission réception électromagnétique permettant de rayonner en. ULB en utilisant un connecteur SMA permettant d'avoir un meilleur gain, une large bande passante, une taille réduite 21,25mm x 22.25mm, une bonne adaptation pour la bande de fréquence X avec un coût de production faible. Elle est constituée d'un seul patch rectangulaire reliée à la sortie par un connecteur SMA. L'antenne est alimentée par couplage électromagnétique. Le point d'alimentation est uni à un connecteur SMA (Figure 7) inséré dans la ligne micro-ruban permettant par la suite d'augmenter le gain, la directivité et la bande passante. Le dispositif selon l'invention est particulièrement adapté aux applications des télévisions par satellites opérant dans la bande X.

Systems and techniques are provided for proximity coupled multi-band antenna. A two-layer flex antenna includes a first element and a second element arranged with a gap between the first element and the second element. A dielectric material covers the two-layer flex antenna and the gap. A thin trace antenna is arranged on top of the dielectric material such that a first portion of the thin trace antenna is partially congruent with the first element of two-layer flex antenna, a second portion of the thin trace antenna crosses the gap between the first element and the second element of the two-layer flex antenna, and a third portion of the thin trace antenna extends away from the second element of the two-layer flex antenna.
Abstract:
Miniature multifunctional antennas and related techniques are disclosed that are capable of wide bandwidth operation. In some embodiments, the antennas are capable of being reconfigured in the field for optimal performance in different frequency band configurations (e.g., a single wide instantaneous bandwidth, multiple smaller bands, etc.) and/or for purposes of self healing. In some embodiments, the antennas can be reconfigured in the field to achieve different polarizations (e.g., vertical, horizontal, circular). The antennas can be implemented in a very compact manner making them ideal for use in devices and platforms where size and weight are a concern.
