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. Q134 Conformal Broadband Antenna - Harris Harris’ Q134 Antenna offers the latest in fully conformal, low RCS antenna. The Q134 antenna capitalizes on Harris’ proven annular-slot technology providing a 3.7:1 operating bandwidth, which exceeds the useful bandwidth of most blades and other exposed apertures. In addition to the broad operating bandwidth, the Q134 also Compact UWB-MIMO antenna with metamaterial FSS decoupling Jun 26, 2017 · 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.
This paper proposes a solution to control the polarisation of the ASA independently from the feeding point position. It also allows an easier impedance matching of the antenna, and thus compact size and broadband behaviour. The concept of a polarization diversity antenna, based on this antenna solution, is then proposed

A compact annular ring microstrip antenna was proposed for a wireless sensor network (WSN) application in the 2.4 GHz band. In this paper the major considerations of the conformal antenna design were the compact size and the impact on antenna's performance of a steel installation base.
Dual-Port Dual-Wideband Annular Slot Antenna with Stable annular slot antenna proposed in [23] provides dual-band feature with two concentric slot-rings and stable radiation pattern in both bands, but the dimensions of the cavity were too large, hence resulting in a bulky structure unsuitable for array design. In this paper, a compact dual-feed dual-band slot antenna is described.
