A planar ultrawideband modular antenna for connection to a feed network. The antenna has a ground plane, and an array of antenna elements spaced from the ground plane, each antenna element comprising a pair of arms.
principle and method of microstrip antenna design. A broadband dual band printed antenna for WLAN is designed in Section 3. In Section 4, a dual frequency dual band microstrip antenna is designed, which is used to realize the dual band operation on the radiation side. Section 5 is the summary of the paper. 2. Design Theory 2.1. Design of a Microstrip-Fed Quad-Band Slot Antenna for WLAN ... The slot antenna fed by the microstrip line is one type of microstrip antenna which has advantages such as low profile, lightweight, simple structure and easy fabrication [1]. For WLAN/ WiMAX systems, some slot antennas have been proposed by using a slot-ring antenna with a narrow rectangular slot [2], parasitic element [3], or A New Compact Slot Antenna for Dual-band WLAN Applications A New Compact Slot Antenna for Dual-band WLAN Appli cations 29 relative permittivity of 4.6. Table 1 summarizes the detailed dimensions of the antenna parameters as labeled in Figure 1.

Design And Analysis Of Compact U Slot Microstrip Patch ... The work started with basic rectangle antenna with resonant frequency 2. 43GHz and bandwidth of 68MHZ, then the same antenna was converted to U -slot patch antenna which resulted into lower shift in frequency of operation at 2. 10GHz. This result shows an area reduction of antenna. The size of this slot antenna is lower than that of Design of Narrow Slotted Rectangular Microstrip Antenna

A novel reconfigurable dual-band patch antenna design using a varactor-loaded slot has been proposed. The frequency ratio tuned from 1.35 to 1.73 with capacitance varying from 0.5pF to 1.1pF. The radiation patterns are similar at both bands. When C = 0.5 pF, the realized broadside gain at both bands is 7.2 and 7.5 dBi, respectively.

Antenna Design A resonant narrow slot antenna is equivalent to a magnetic dipole, and at its first resonant frequency it has an equivalent length of ( is the guided wavelength in the slot). If the slot antenna is fed near an edge by a microstrip line and the slot width is properly chosen, at a frequency above the first slot res- TAPERED MEANDER SLOT AND COPLANAR SLOT ANTENNA … A compact meander-type slot antenna with 56% size reduction has been reported in [3] in which non-uniform slot line widths give rise to lower operating frequency of the antenna. In this paper we show that a dual-frequency operation is achieved by using a tapered meander slot antenna with a short-ended microstrip line feed. The
