Download Citation on ResearchGate | Design of Wide-Band, High Gain Microstrip Antenna Using Parallel Dual Slot and Taper Type Feedline | In this paper, we have designed and fabricated a wide-band ... Slotted array antenna with single feedpoint - EMS ... Within this cavity of the antenna assembly, the centrally-located center bar 40 creates two waveguide channels 54a and 54b, whereby the center bar 40, the rear plate 42, and the face plate 44 form the walls of the waveguide channels. In particular, the waveguide channels 54a and 54b share a common wall represented by the center bar 40.
The antenna feed comprises an open cup-shaped conductive cavity wherein the two orthogonally mounted feeding elements of the antenna located within its volume, are low cost printed circuit board elements.

A patch-fed cavity is developed for linearly polarized applications, while for circularly polarized antennas, the microstrip patch is replaced with a circularly polarized dielectric resonator. The cavity antenna produces a gain of 12 dB over a 700MHz band- width at K-Band (20GHz) and over a 1 GHz bandwidth at Ka-Band (30GHz). Low-Cost Wideband and High-Gain Slotted Cavity Antenna Using ... Abstract: A novel single-fed low-cost wideband and high-gain slotted cavity antenna based on substrate integrated waveguide (SIW) technology using high-order cavity modes is demonstrated in this paper. High-order resonant modes (TE130, TE310, TE330) inside the cavity are simply excited by a coaxial probe which is located at the center of the ... Cavity backed dual slot antenna for gain improvement - Li ... A simple method of gain improvement for the cavity backed slot antenna based on the substrate integrated waveguide technique has been presented in this article. By using dual slot at the cavity edges to substitute a single slot at the cavity center as the radiating element, gain of the cavity backed slot antenna has been improved about 1.7 dB ... DESIGN OF A HIGH-GAIN CAVITY-BACKED SLOT ANTENNA WITH ... superstrate-covered cavity-backed slot antenna as described in [16{21] was between 9.8 and 16.7dB. In this paper, a simple backed slot antenna with regular one single-layer superstrate is introduced. The gain is improved by modifying the ground plane orientation, adding a small number of square mushroom cells to suppress side radiation, and ...
