Patent number: 8803749Abstract: An elliptically polarized (EP) dielectric block antenna comprises a linearly polarized (LP) dielectric block antenna and a wave polarizer integrated with the LP dielectric block antenna. The wave polarizer converts the LP wave of the LP dielectric block antenna into an EP wave or a circularly polarized (CP) wave. The wave polarizer is directly integrated with the LP dielectric block antenna by fabricating inclined slots on faces of the dielectric block at an oblique angle to the LP wave direction of polarization. This provides a very compact EP or CP antenna with a broadside or omnidirectional radiation pattern. The EP or CP antenna is excited by an inner conductor of a SubMiniature version A (SMA) connector that can be directly connected to a coaxial line thereby providing a simple feed network for the antenna.Type: GrantFiled: March 25, 2011Date of Patent: August 12, 2014Inventors: Kwok Wa Leung, Yong Mei Pan, Kai Lu

Publication number: 20100210987Abstract: A breathable medical adhesive tape includes an air-permeable substrate, such as a non-woven fabric, a cotton fabric, or a nylon sheet having air pores, having a surface on which a layer of adhesive is applied. A plurality of continuous non-adhesive-coated air-transmittable patterns is formed in the adhesive layer of the air-permeable substrate. The non-adhesive-coated air-transmittable patterns are formed by employing a scrape mechanism to scrape off a portion of the adhesive from the adhesive layer of the air-permeable substrate. The adhesive tape is advantageous in more effective dry-keeping, enhanced adhesion, and reduced allergy caused by excessive adhesive.Type: ApplicationFiled: February 17, 2009Publication date: August 19, 2010Inventor: HSIN-KAI LU
