Llacer, “A broadband pattern diversity annular slot antenna,” IEEE. Trans.
A rectangular slot antenna fed by microstrip line is proposed, which produces a very large bandwidth on a relatively thin substrate. Simulated and measured results show that there is an improved bandwidth, a relatively stable pattern and that its fabrication is easier than that for the conventional slot antenna.
Annular Slot Antenna - How is Annular Slot Antenna ... In [12], dual-band circularly polarized annular slot antenna is obtained by employing two square slots, a bended microstrip line and a cavity back. As shown in Figure 2(a), antenna 1 is a fold annular slot antenna , and the asymmetric of the slot width will lead to two split orthogonal degenerate modes around 2. Design of a compact UWB antenna for mimo applications by ...

Two antenna elements are placed side by side and fed with matched microstrip lines on a substrate with an area of 35 × 30 mm 2. Notched characteristics at WiMAX (3.4–3.6 GHz) and WLAN (5.725–5.825 GHz) have been achieved using complementary split ring resonator (SRR) slots etched in both the antenna elements.
Broadband annular slot antenna with polarization diversity ... 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 TANGENTIALLY FED BROADBAND ANNULAR SLOT ANTENNA FOR WLAN ...

A hand-held antenna specifically for GPS applications is provided which includes a microstrip patch antenna having a ground board, a single radiating patch spaced from the ground board and a resonant cavity defined between the ground board … US4035807A - Integrated microwave phase shifter and radiator… The antenna structure defined in claim 12 wherein said radiating means in each module is a slot radiator within a predetermined area of a ground plane on one side of said substrate.
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. It has been ... Dual Port Ultra Wideband Antennas for Cognitive Radio and ...
