“…As most of modern systems use two or more frequency bands, for example WLAN standard IEEE 802.11 operating at 2.4-2.45 GHz and 5.15-5.85 GHz and WiMAX IEEE 802.16 standard operating at 2.3-2.7 GHz, 3.3-3.9 GHz and 5.15-5.85 GHz bands, the implementation of dual-band antenna integrated with band select filters becomes more practical solution then usage of diversity antenna. This approach, together with novel architecture of dual-band front end, was presented in [1].…”

A low profile microstrip dual band antenna with conductor backed coplanar waveguide (CBCPW) feed is proposed for wireless local area network (WLAN) applications. In conventional CPW feeding, the upper surface of the antenna substrate has a centre strip conductor with semi-infinite ground planes on either side. The CBCPW fed antenna has an additional metallic coating at the back side of the substrate. The extra coating not only provides mechanical support to the substrate, but also works as a heat exchanger for electronic circuits with active devices. The antenna is designed on a flame retardant woven glass reinforced epoxy resin (FR4) substrate having permittivity 4.4 and loss tangent 0.02. The proposed design has achieved dual band operation with a compact size of 20×20×1.6 mm 3 . The IE3D software simulation results show that the proposed antenna has a good bandwidth efficiency at 2.59/5.38 GHz and it meets the necessities of IEEE 802.11 standard.

“…The dual-band filter-antenna investigations are relatively few. In [11][12][13], the dual-band filter and antenna, which have been designed separately with the 50 Ω constraint, are then connected together using 50 Ω transmission line. Because the filter and antenna respective input/output ports are not perfectly matched with the 50 Ω, the impedance bandwidth or selectivity at the input/output port of the filter-antenna is worse.…”

Abstract-A co-designed compact dual-band filter-antenna suitable to be embedded inside a wireless access point (AP) in the 2.45/5.2-GHz wireless local area network (WLAN) bands is presented. The proposed filter-antenna comprises a loop-loaded dual-band monopole radiator and a microstrip dual-band pseudo-interdigital bandpass filter. The monopole consists of a uniform width monopole, two identical capacitively loaded magnetic resonators and a top loaded loop. The two magnetic resonators are loaded at the center of the monopole for dual-band operation and the rectangular loop loaded at the top is involved for miniaturization. Instead of using the traditional 50 Ω interfaces, the impedance between the filter and antenna is optimized to improve the performance. The filter-antenna and the system circuit board of an AP share the same substrate and ground plane. In this case, the design can fully integrate the circuit board of the AP into an internal filter-antenna solution. The proposed filter-antenna provides good selectivity and rejection in out of band regions and omni-directional radiation patterns within the two desired bands. The measured results show good agreement with the simulated ones.
