The waveguide slot antennas we will be discussing have longitudinal slots in the broad face of stan-dard rectangular waveguide, parallel to the length of the guide. Figure 7-1 is a photograph of a typical waveguide slot antenna, with a total of 12 slots, six on each side, in WR-90 X-band waveguide for 10 GHz operation. Microstrip Patch Antenna Designing at 2.4 GHz Frequency Microstrip Patch Antenna − Designing at 2.4 GHz Frequency. 129 . 2. Designing For designing of a microstrip patch antenna, we have to select the resonant frequency and a dielectric medium for which antenna is to be designed. The parameters to be calculated are as under. Width (W): Non-Resonant Slotted Waveguide Antenna Design Method

Compact Rectangular Slot Patch Antenna for Dual Frequency ... This paper presents the design and simulation of a compact rectangular slot patch antenna for dual frequency operation at 2.4 GHz and 5.2 GHz using the inset feed technique. The simulation of the designed antenna was done with the aid of computer simulation technology (CST) microwave studio version 12. Printed Wide Slot Ultra-Wideband Antenna - InTech - Open within the entire UWB. The design of a printed wide-slot antenna with a rotated slot is pre‐ sented in [20]. The impedance bandwidth of the antenna varies with the rotation angle of the slot and can maintain 50.2% with suitable angle. More recently, the design of a printed wide-slot antenna for wideband applications is proposed in [21].
proposed slot antenna conflgurations and design procedures are given; the experimental results are also given and discussed. 1. INTRODUCTION Microstrip-fed slot antennas (MFSA) ofier many attractive features such as low proflle, high power capacity, high fabrication tolerance, and ease of integration with printed circuits. Thus they are
Antenna “efficiency” is different than antenna “Gain”. Antenna efficiency quantifies the resistive loss of the antenna in terms of the proportion of power that is actually radiated versus the power that is first delivered to it.
A simple and compact design of solar-slot antenna for dual band 2.4/5.2GHz wireless local area networks (WLAN) applications is proposed.

Owing to the additional capacitance contributed by a stub-protruded feedline and two symmetrical stubs at the slot edge, the impedance-matching condition is improved; meanwhile, the resonance frequency of the monopole slot antenna is significantly shifted down, and an
Design procedure of a U-slot patch antenna array for 60 GHz MIMO application Abstract: In this paper, we present an antenna array with beam steering capability to characterize MIMO channels over 57-63 GHz frequency band. This uniform linear array is built of six U-slot patch elements which are spaced half wavelength to maximize the beam ...
