Title
A novel microstrip-fed dual-band printed antenna for wireless local area network (WLAN) is presented. The antenna comprises a rectangular and a circular radiating element, which generate two resonant modes to cover 2.4/5.2/5.8 GHz WLAN bands. 43 designed the dual- and wideband slot loaded stacked microstrip patch antenna for WLAN/WiMAX applications. The bandwidth of the proposed dual-band antenna at lower resonance frequency is 9.53%, whereas at upper resonance frequency, 6.95% is achieved. 2.4 Parasitic MSAs. Ring slot 1, L slotted microstrip fed monopole antenna2 indicates that the antenna proposed in this paper is relatively compact and simple in design, which would prove to be beneficial in manufacturing the antenna. In this paper, a T shaped patched antenna is presented which covers the WLAN 2.4 GHz and WiMAX 2.4 GHz.
The surface is the integration of a metasurface at the S-band and a partially reflective surface (PRS) at the Ka-band. The resonant mode of the metasurface is excited by a microstrip-fed slot, and the PRS with a pair of substrateintegrated waveguide (SIW)-fed slots are employed to form a Fabry- Perot resonator antenna (FPRA).

Abstract
A Dual Band Microstrip-fed Slot Antenna Tuner
A compact dual-band annular-slot antenna loaded by a concentric split-ring-slot is presented. A stepped microstrip feedline enables the control of the coupling and provides good matching. The annular-slot is connected to the split-ring-slot by a rectangular slot, which increases the surface of the current path, thus notably reducing the resonant frequency for a given size. The embedded split-ring-slot structure allows many resonant modes to be realised. By tuning the key parameters, these operating modes and their bandwidths can be controlled. A wide bandwidth can be realised for either the lower band, upper band or both bands simultaneously, depending on the application. Measured results show that the bandwidths in the region of 45-15% and 32--8.4%, can be provided for the lower and upper bands, respectively. For the case where a wideband response is required for both bands, it is shown that 26 and 32% can be realised. A 30%miniaturisation is also achieved compared with conventional annular ring slot antennas.
