20090135066 | Internal Monopole Antenna - The invention relates in one aspect to antenna useful with for example a flat a radio device. In one embodiment, the antenna comprises and internal monopole antenna that has an arrangement for improving its characteristics, including a planar monopole radiator and an auxiliary element. The auxiliary element can be a mere conductor strip, or a ceramic plate partly coated with a conductor for example. The conductor of the auxiliary element is connected to the ground at a point (SP), which is relatively close to the feed point (FP) of the planar element. The planar element can be shaped to form two operating bands for the antenna. The auxiliary element can be used to increase the bandwidth of the internal monopole antenna and/or to improve the omnidirectional radiation of the antenna. | 05-28-2009 |

20110181476 | MINIATURE PATCH ANTENNA AND METHODS - A miniature patch antenna element useful for wireless applications such as portable radio devices, and methods for using and manufacturing the same. In one embodiment, a plurality of discrete ceramic elements creates a spatially loaded miniature patch antenna. Ceramic material is placed only at locations where it achieves the desired effect on reducing the physical length of a half-wave radiator. In one variant, these locations comprise the edges of the half-wave radiator (e.g., metallic plate). This configuration advantageously has lower weight, smaller size and reduced cost that result from using less ceramic material in the construction of the antenna. Moreover, RF performance of the antenna is improved as compared to a fully ceramic construction, as electric field losses in the spatially loaded antenna structure are reduced as well. | 07-28-2011 |
20110260939 | DISTRIBUTED MULTIBAND ANTENNA AND METHODS - A distributed multiband antenna intended for radio devices, and methods for designing manufacturing the same. In one embodiment, a planar inverted-F antenna (PIFA) configured to operate in a high-frequency band, and a matched monopole configured to operate in a low-frequency band, are used within a handheld mobile device (e.g., cellular telephone). The two antennas are placed on substantially opposing regions of the portable device. The use of a separate low-frequency antenna element facilitates frequency-specific antenna matching, and therefore improves the overall performance of the multiband antenna. The use of high-band PIFA reduces antenna volume, and enables a smaller device housing structure while also reducing signal losses in the high frequency band. These attributes also advantageously facilitate compliance with specific absorption rate (SAR) tests; e.g., in the immediate proximity of hand and head “phantoms” as mandated under CTIA regulations. Matching of the low-frequency band monopole antenna is further described. | 10-27-2011 |
20130088404 | MULTI-FEED ANTENNA APPARATUS AND METHODS - A space efficient multi-feed antenna apparatus, and methods for use in a radio frequency communications device. In one embodiment, the antenna assembly comprises three (3) separate radiator structures disposed on a common antenna carrier. Each of the three antenna radiators is connected to separate feed ports of a radio frequency front end. In one variant, the first and the third radiators comprise quarter-wavelength planar inverted-L antennas (PILA), while the second radiator comprises a half-wavelength grounded loop-type antenna disposed in between the first and the third radiators. The PILA radiators are characterized by radiation patterns having maximum radiation axes that are substantially perpendicular to the antenna plane. The loop radiator is characterized by radiation pattern having axis of maximum radiation that is parallel to the antenna plane. The above configuration of radiating patterns advantageously isolates the first radiator structure from the third radiator structure in at least one frequency band. | 04-11-2013 |
20130162486 | SWITCHABLE DIVERSITY ANTENNA APPARATUS AND METHODS - An active diversity antenna apparatus and methods of tuning and utilizing the same. In one embodiment, the active diversity antenna is used within a handheld mobile device (e.g., cellular telephone or smartphone), and enables device operation in several low frequency bands (LBs). The exemplary implementation of the active LB diversity antenna comprises a directly fed radiator portion and a grounded (coupled fed) radiator portion. The directly fed portion is fed via a feed element connected to an antenna feed. The coupled fed portion of the LB antenna is grounded, forming a resonating part of the low frequency band. A gap between the two antenna portions is used to adjust antenna Q-value. Resonant frequency tuning is achieved by changing the length of the grounded element. The LB feed element is disposed proximate the feed element of a high band diversity antenna, thus reducing transmission losses and improving diplexer operation. | 06-27-2013 |
