A radial line slot antenna (RLSA) is a nonresonant multimode waveguide slotted array. To improve the power handing capacity, we design a radial line slow wave structure which replaces a traditional dielectric sheet. At the same time, the structure of the radiator unit is redesigned and optimised. Radiation properties of PIFA | 3. EBG-PIFA ANTENNA … One of the current constraints on antenna design for small hand-held devices such as mobile phones, personal digital assistants (PDAs), and wireless wearable computers is the limitation of design space, particularly for some internal antennas such as printed dipoles, meander- line, antennas and planar...

A T-antenna, T-aerial, flat-top antenna, or top-hat antenna is a capacitively loaded monopole wire radio antenna [1] used in the VLF, LF, MF and shortwave bands. [2] [3] [4] T-antennas are widely used as transmitting antennas for amateur …
A radial line slot antenna (CP-RLSA) is a slotted waveguide planar array for DBS reception. A number of designs have been devised, but these designs have pros and cons. In order to suppress grating lobes and increase the gain, this article will introduce a new wave material =1.06...

Designs and Experiments of a Novel Radial Line Slot …
Characteristics of small-aperture, single-layered, radial ... A radial-line slot antenna (RLSA) is a high-efficiency planar array. A double-layered radial line and uniform slot length have been adopted in conventional RLSAs. A single-layered RLSA is much simpler in structure, but the slot length must be varied to synthesise uniform aperture illumination.
US9966656B1 - Broadband rectenna - Google Patents A rectenna for high efficiency RF-to-DC wireless energy harvesting that includes an off-center-fed dipole antenna and a rectifying circuit, wherein the rectifying circuit comprises at least one rectifying diode. Folded unipole antenna - Wikipedia The folded unipole antenna is a type of monopole antenna; it consists of a vertical metal rod or mast mounted over a conductive surface called a ground plane.
