Title
(EN) DUAL POLARIZED UHF ANTENNA
(FR) ANTENNE UHF À DOUBLE POLARISATION
Abstract
(EN)
Described are antenna assemblies and methods for forming antenna assemblies. An antenna assembly (200a) includes a dual polarized far-field antenna (210) and a near-field loop antenna (120). The near-field loop antenna is electromagnetically coupled to the dual polarized far-field antenna. The near-field loop antenna includes two contacts for electrically connecting to a chip (110).

La présente invention se rapporte à des assemblages d'antennes et à des procédés pour former des assemblages d'antennes. Un assemblage d'antennes (200a) comprend une antenne en champ éloigné à double polarisation (210) et une antenne cadre en champ proche (120). L'antenne cadre en champ proche est couplée électromagnétiquement à l'antenne en champ éloigné à double polarisation. L'antenne cadre en champ proche comprend deux contacts permettant de réaliser une connexion électrique avec une puce (110).
