Broadband pattern diversity annular slot antenna

By author

A compact asymmetric coplanar strip (ACS)-fed ultra-wideband (UWB) antenna for diversity applications is presented. The proposed antenna is composed of two circular radiating elements and orthogonal ACS-fed mechanisms to achieve diversity performance across the UWB from 2.66 to 11.08 GHz, and occupies a very compact size of 28.5 × 28.5 mm2. By introducing a rectangular stub diagonally between ...

Dual-Band Microstrip Patch Antenna for Wireless Applications Keywords: Microstrip, dual-band, wireless, wide-band, slot-loaded Abstract A small wideband microstrip patch antenna is introduced. The antenna is designed to function in the 5-6 GHz wireless LAN bands. It achieves multi-band functionality through the addition of a slot to a square patch (21 mm by 21 mm by 2.6 mm). Dual-polarization and dual-pattern planar antenna for ...

The annular ring slot antenna can be useful for the implementation of a pattern/polarization receiving diversity scheme in on-body and off-body communication systems. Diversity gain measurements in both an anechoic chamber and an actual indoor environment are being performed, for different body positions and typical body movements, as already ...

To realize antenna system miniaturization and integration, silicon material is applied as substrate. The proposed antenna becomes a very compact construction with dimension of 38.2 × 26.6 × 0.4 mm 3. The proposed broadband FSS unit consists of four split rectangles and one I-shaped strip. Four Ports Wideband Pattern Diversity MIMO Antenna Four Ports Wideband Pattern Diversity MIMO Antenna . Ramling P. Manurkar α & Veeresh G. Kasabegoudar σ. Abstract- In this paper a broadband four ports MIMO antenna with pattern diversity is ... Design of microstrip-fed printed UWB diversity antenna ... The antenna in shows the pattern diversity and polarisation diversity and covers the lower UWB of 3.1–5.15 GHz. The isolation for this diversity antenna is better than 26 dB. In , antenna system for pattern diversity is proposed having dimension of 80 mm × 80 mm. The antenna system has impedance bandwidth from 3 GHz to 12 GHz.

The proposed antenna facilitates nearly Omni directional radiation pattern, low envelope correction coefficient, moderate gain, and efficiency. Moreover, BROADBAND ARRAY ANTENNA - Cobham plc pattern control and unique machined/angled apertures to solve difficult installation problems. Also available are special horn designs with bandwidths up to 9:1. These offer the clear advantage of using one antenna to cover larger frequencies instead of having several antennas covering the same frequencies. Nurad currently offers existing horn Design of Broadband Microstrip Patch Antenna Using Stack and ...
