Design narrow slot antenna for dual frequency

Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear.

A single narrow slot radiator can also work on frequencies ±5 … ±10% besides its resonance frequency. For array antennas, this is not possible so easily. Such a group antenna is fixed strongly to a single frequency, which is determined by the spacing of exactly λ g , and for which the antenna … Design of Narrow Slotted Rectangular Microstrip Antenna Design of Narrow Slotted Rectangular Microstrip Antenna Antenna design Designing an antenna in the Wi-max ... Lu JH, Tang CL, Wong KL, ‘Novel dual-frequency and broadband designs of the slot-loaded equilateral Rectangular Microstrip Antenna’ IEEE Trans. Antennas Propag. Design A Dual-Frequency Rectangular Patch Antenna The design graphs are then used to compute the dimensions of a rectangular patch and feed network for a dual-frequency antenna for use at 1.9 and 2.4 GHz. For the feed network, two transmission lines are used to connect the two edge feeds to an open circuit stub to match the antenna at the two frequencies. Design of Compact Multiband Slot Antenna for Wideband Abstract A compact multiband slot MIMO antenna is presented with three frequency bands for Ultra wideband (UWB) applications using defected ground structure (DGS). The overall dimension of the antenna is 27.1×30.8×1.6mm3. The simulated return loss, isolation, radiation pattern, gain, directivity are presented using advanced design software (ADS).

A single narrow slot radiator can also work on frequencies ±5 … ±10% besides its resonance frequency. For array antennas, this is not possible so easily. Such a group antenna is fixed strongly to a single frequency, which is determined by the spacing of exactly λ g , and for which the antenna has been optimized.
