This curve shows that the antenna resonate at two frequency.Fig 4 & 5 shows the Elevation pattern curve of dual frequency circularly polarized microstrip antenna at frequency 7.44 and 7.1 GHz respectivaly.Fig 6 shows the smith chart of the proposed design. Slot Antenna Uses Dual Polarization | Microwaves & Radio As will be shown, however, it is possible to obtain broadband frequency operation with a dual-polarized-antenna design. The antenna, excited by two coaxial-line feeds, is composed of four T-shaped slots and four cross-shaped slots in the radial directions of a circular patch.

In thi s sllldy, dual-frequency slot-loaded rectangular microstrip antennas were designed, fabricated and evaluated. The design consists of rectangular patch microstrip antenna loaded with a pair of narrow slots parallel and close to the radiating edges on the patch, which is feel by centre-fed microstripline feed .
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.

Wideband Microstrip Antenna Design Scott A. Wilson, Graduate Student Radar and Communications Lab Department of Electrical Engineering Penn State University, State College, PA DESIGN GOAL Design a broadband microstrip antenna operating over the 450-700 MHz frequency range with a gain of at least 8 dB.
A. 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- Radar Basics - Slot Antennas 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.
